​@@ipMalikSir, What if windows 10 is out of support?

@@cyogeshkc7682 Sorry, but I didn't understand your question.. After all, support for Windows 10 will end in 2025. Or did you say about your Windows 10? How does this problem manifest itself? please tell me more details.

Well, I'm glad I could help you 🙂

Ok!

@bjorn9595 I'm Finding The Same , Have You Got Any Solution Till now ?

you will have to install an alternate boot loader / boot manager like Grub2Win for example

To be completely safe when using two operating systems on two different physical disks, you must install the OS on the first disk while disabling the second disk, then install the OS on the second disk while disabling the first disk. Then you will boot disks not using the bootloader, but using the Boot Menu, this is the most reliable and safe way to use different OSes on different Physical disks. Yes, it’s difficult to physically remove NVME, but maybe you can do it once when you install the OS on another disk? Or you can try to disable NVME in the BIOS, my BIOS does not have such a function, most likely it depends on the motherboard model, but in my BIOS you can disable all SATA drives without problems, and without having to pull out the cables from the drives, you can do this in the BIOS not difficult at all.

Installing Windows XP on a modern PC is the problem...

A virus program is active only after starting the OS where the virus itself is located. The second OS is not running at this time, so the virus cannot penetrate the disabled OS.

Hi, to install XP on a modern computer you need certain programming skills. ru-vid.com?search_query=install+XP+on+a+modern+PC

go to create and manage disk partition in windows right click on other window's C drive change letter to none ... it will not show in that windows .. do it in each windows

Yes, It is possible

You can boot any of these discs using the Boot Menu. Immediately after turning on the computer or after restarting it, you need to press a certain keyboard key and, after opening the Boot Menu, select the required disk.

Yes, sure!

There are several reasons for this problem, try to find the one that suits you: ru-vid.com?search_query=A+required+media+driver+was+not+found+during+Windows+installation

You can install different OS on different partitions

Yes, Windows 7 can be installed in the same way. The only thing is that there may be problems with the hardware when installing Windows 7, because it is already a rather old program..

Tell us about your problem in more detail, after which step the problem arose and please indicate the time of viewing when the problem, time code. For example 02:30 And I will try to help you.

If two Windows are installed on two physical disks, you will always see the other disk when opening This PC. Perhaps I didn't understand your question.. You can disconnect the SATA cable from the second drive, you can also disable the second drive in the BIOS and then when you open This PC you will not see the drive with the second Windows and you will not have access to it.

@@ipMalik Thanks i did not know i can disable disks in BIOS

@@modra1222 Ok! ru-vid.com?search_query=how+to+disable+a+disk+in+BIOS

I think I have an thing that can upgrade your Windows to pro, also do you want windows 10 pro or windows 11? And do you have another computer/laptop?

To install Windows on a second physical disk, and then format the first disk and use it as data storage, do the following: 1. Prepare a bootable USB flash drive to install new Windows on the second disk. 2. Turn off the computer, unplug the power cable or SATA cable from the first drive, and connect the second drive to the computer. 3. Install new Windows on the second disk. 4. Turn off the computer and connect the SATA cable or power cable to the first drive. 5. Turn on the computer and immediately call up the boot menu, select the second disk and press Enter. Now you can transfer the necessary files from the first disk to the second disk, then format the first disk and this will not affect Windows on the second disk.

@@ipMalik thnx for fast response but i dont want want to format the second disk only the old c partition where windows 10 is installed and i dont want to affect my 2 other partitions this drive is in a laptop and also HDD not SDD if it makes a difference do i have to remove it before installing windows 11 on my new m.2 nvme if i keep it will it affect my d and e partitions ?

@@cenation7mjc Installing a new Windows on a new disk will not affect partitions D and E in any way, pay attention to the disk selection window, the time stamp in my video is 10:11, in this window you need to indicate exactly which disk or partition you will install the new Windows on.

@@ipMalik so i tried and my system was MBR and the instalation it said cannot be installed to this disk on EFI system, windows can only br installed to GPT disks

Adding more i formation to clarify I tried converting the new SSD to GPT now it said it cant be installed on GPT but allowing me to select the old MBR which i didnt try since i dont want I also made a 300gb partion on the SSD to backup important data both times i tried to install Now i think i have one of 3 solutions 1 change the main HHD to GPT idk how safe this is for my data 2 open the laptop again and disconnect my hard drive and install the windows on the solo SSD GPT but i dont know if this will mess with the MBR drive when i put it back (i didnt want to remove it in the first place ) 3 delete all partitions on the GPT SSD ? I heard this helps but idk if they mean all partitions from all drives

If you change the drive letter that already contains Windows or applications, the applications may have problems starting or finding the drive. To avoid problems, I recommend not changing the drive letter of a drive that already contains Windows and applications. Try setting the path in each Windows project to the drive letters that Windows sees.

@@ipMalikMy situation may be like this: I have three physical drives: C, D and E So currently windows is installed in C and projects files in D. I want to install another windows 10 in E But I want my projects files always to be in a drive with letter D, I don't want it to be another letter when starting with the other windows in E How to ensure drive with projects files will have same letter?

@ Now I understand your question. Before installing Windows 10 on drive E, you need to turn off the computer and disconnect the SATA cables from drive C and drive D, or you can disable these drives in the BIOS. After installing Windows 10, reconnect drive D, and it will be detected as drive D. After that, turn off the computer and connect drive C. Then turn on the computer, load Windows 10 and now drive C will be detected as drive E. If I explained something unclearly, ask me and I will answer.

@@ipMalik Crystal clear, 👍

@ OK😊 Plus, I recommend periodically saving disk images from different OSes using Acronis, and storing these images just in case - I do this all the time. This is convenient, useful in case of various failures in the OS and safe: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-7QRLddgH3fg.html

This is easy to do: On disk 1, open This PC, find the second disk with Windows that you want to remove, right-click on this disk and select “Format”.

Yes, when installing a second Windows you will get this problem and this happens because the new Windows “sees” the first OS. But there is a way to get around this problem and to do this you need to do the following: 1. Before installing Windows number 1, disconnect the SATA cables from all other drives of your computer, and of course, before disconnecting and connecting the SATA cable to the drives, you must turn off the computer every time. If there are other drives connected to your computer for storing data, then they should all be disconnected until you install both Windows on two drives. 2. After installing Windows number 1, disconnect the SATA cable from the drive with Windows number 1 and connect the drive on which you will install Windows number two. 3. After installing Windows 2 on the second disk, turn off the computer again and now you can connect SATA cables to all disks. When you finish all this, turn on the computer and enter the BIOS, open the Boot tab and in boot priority put in first place the disk with Windows that you will use most. Press F10 and save changes. The computer will reboot and Windows will automatically be loaded, which you set first in the BIOS as a boot priority. 4. To boot your computer with Windows number 2, you need to turn on or restart the computer and immediately call the Boot Menu, in this menu you can select the Windows you need.

@@ipMalik Hi. Thanks for the quick response. Unfortunately, the issue I have here could be more complex. I am trying to install these system son M.2 (NVME) drives, which makes disconnecting them much more awkward. I have tried installing both systems with both drives in, and it didn't work. After that, I removed one drive and installed the second system again, but I couldn't load it up after inserting the drive with the first system. I have installed the first system again, with the second one still connected to the PC, and it worked??? I am still trying to understand why Windows decided to see both bootloaders this time. It is a mystery which I may never solve :D Anyway, thank you for your help :)

@@jamjestrysiek Hi. Yes, Windows sometimes gives us riddles🙂 Of course, connecting and disconnecting NVME is much more difficult than HDD or SSD, but if you do as I suggested in the previous comment, then in the future you will NEVER have problems with the Windows bootloader. I assume that when installing the OS on two different physical disks, the problem with the Windows boot loader occurs for the following reason: At the time of installing Windows number 1, the bootloader can install Windows on drive C on the first NVME drive, and the bootloader sends a small system partition or some element of Windows number 1 that supports the operation of the OS to drive 2 NVME. When you start installing Windows number 2 on the second NVME disk, the bootloader formats the second disk and deletes the small system partition that belongs to Windows number 1. As a result, Windows number 1 stops working.. After that, you again install Windows number one on the first disk, and if its small system partition ends up on the second disk, Windows 1 will work without problems. But if you reinstall Windows number 2, or some problem happens to Windows number 2, then Windows number 1 will stop loading again. On the computer where I do most of my work, two SSDs are connected and different Windows are installed on each disk, which I installed independently of each other in the same way as I told you in the previous comment. I do the main work in Windows 11 on disk 1, on the second disk I constantly reinstall various OSes, which is necessary for my activities, and before each installation I disconnect all other disks from the computer so that there are no problems with the bootloader.

@@Ji-James So, does it mean tnat if I will lose the system which was installed as the second, I will also loose ability to log to both of systems?

@@jamjestrysiek This will depend on the reason why the second OS is lost - if you simply reinstall the second system or format the second disk, then the bootloader that supports loading the first OS may be deleted along with the files on the second disk. I will also add that this fact may not necessarily happen, that is, not 100%, but it may well happen depending on how the OS was initially installed and which OS was installed as number 1 in Boot Priority. Something like this has already happened on your computer when you lost access to one of the OS. Only disconnecting all disks from the computer except the one on which you will install Windows will protect against this kind of problem. Moreover, the disconnection does not have to be physical, that is, disconnecting the SATA cable or, in your case, disconnecting the NVME from the motherboard; you can also disconnect one of the drives in the BIOS before installing the OS and not remove the NVME from the computer. After installation in the BIOS, disconnect the disk with the new OS and connect a second disk to install the second OS. I hope that now I have told you everything in detail.

Yes, of course - if the laptop has two physical disks.

I believe you can just repeat the steps, but i'm not sure tho

To install Windows on an external drive, you need a completely different method: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-P3CgiibnTrw.html

I don't understand why you need to install Windows 10 on two disks... They will work without problems

It's not difficult to do: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-zB2fKghMyfA.html

Yes, sure! But if your computer supports Windows 11 and XP

@@ipMalik Hello, can I have two systems of the same version? Let's say two 11s? Thank you.

@@h0nza_ Hello, yes, of course you can. Any 2 or even 3 operating systems installed on different disks will work independently of each other without problems.

@@ipMalik Thank you! I know it was a stupid question, but better be sure :D

@@h0nza_ Your question wasn't stupid, it's the question of a careful person☝

You gave too little information and I did not understand your question.. Please tell me in more detail what you want to know.

To install Windows 11 on an unsupported computer or laptop, two methods work fine: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-s-8Fr5TRoiM.html Or this method, it's much simpler: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-DLk7D4lIKHQ.html

Yes, method. which used for your laptop also works great!

??

Do you want to do this on a laptop or a desktop computer?

@@ipMalik laptop sir, i was planning to buy an ssd +caddy and replacing my dvd slot with it Its supposed to be just for backup but im thinking why not installing windows 10 on it too. (My current os is windows 7)

@@Hyde_Tolut I understood you. If you connect the SSD yourself, then apparently it will not be difficult for you to do the following: 1. Before connecting the second drive, make a bootable USB flash drive for Windows 10 2. Connect the SSD to the laptop and disconnect the drive with Windows 7; to do this, you can remove the SATA cable or power cable from the drive with Windows 7. 3. Connect a bootable USB flash drive to the laptop and install Windows 10 on the SSD; installing a new Windows 10 in this way will not affect the disk with Windows 7 in any way. 4. After this, you can reconnect the cable that you disconnected earlier to the Windows 7 drive. 5. Immediately after turning on the laptop, enter the BIOS, and in the Boot section, set the boot priority to the first disk that will be your main one. 6. You can also choose which Windows to boot using the Boot Menu, that is, after turning on the laptop, you need to call up the Boot Menu, select the required disk and press Enter. This method of installing two OSes on two physical disks is the safest for saving data on both disks.

@@ipMalik ah, i was reading something similar in some forum about needing to disconect the main disk before installing, but im not quite sure how or why, i will try this when i get the new disk thanks a lot for the help sir, thank you for your time, appreciate it a lot.

@@Hyde_Tolut If you install Windows 10 on the second disk, you need to disconnect the first disk so that later the two Windows can work independently of each other. Then any problem on one of the Windows will not affect the other Windows.

I'm sorry, but I have to use a robotic voice for the only reason - I just have bad diction... Alas..

And

So

I don’t know what exactly caused your reluctance to watch this video, but I can say in advance that when I said “computer”, I meant a desktop computer, which includes a separate system unit, a separate monitor and a separate mouse😊

It's not that serious
