I’m about to take a sledge to this pc and just buy a new one bro after 2 years and ppl still replying

Even after 1 year you still help me and others with this problem and you even have other troubleshooting fixes. Im very happy with people like you who want to help others

Omg you just fixed my computer after trying for 2 ENTIRE DAYS thanks!

This helped us. Thank you so much sir. My girlfriend was on a training program online for homebased job when suddenly the computer restarted and we got this error message. I am not a computer expert so I did search right away for a solution through RU-vid then I found this 3min video. She was able to get back on her meeting no more than 6mins. She was very happy, she almost got her job application compromised because of that error and this video saved her from getting eliminated on the training. Thanks alot.

Checked a number of online help videos. This was the first to mention checking the cables to the drive. You've guessed it - the sata cable to the SDD was loose. One firm push and she rebooted. Thank you.

2 years later and your still an absolute life saver, my pc has been having issues for the past year and I’d only just fixed an issue, I was about to have a heart attack when I seen this boot up. Thank you for this, short simple and friendly to the not so “tech savvy”

Video is over 2 years old and still helping people. Thank you

when I encountered this problem I immediately went to youtube and after watching a lot of videos only yours helped! Thank you so much!

I just had a scare like this and I want to say THANK YOU SO MUCH! My Bios is an ASROCK but your fix it tips still helped me (plus assistance by my eldest bro) reboot my PC today. My house had a power outage out of no where today that lasted almost 2 hours, and when I turned my PC on I got that system reboot message. I had to boot up my WiiU to find you! You saved my 1 and only PC. God bless you!

Thanks so much. I need to learn about Linux and I've been on laptops for years. I started my old 2013 Windows 8 desktop and I got the message 'Reboot and select proper boot device'. I followed your instructions and I found out that there was a loose connection to the hard drive. I then saw in Bios that the machine was not booting to my drive where Windows was installed. I saved and restarted and Viola! I'm so impressed with your simple and easy-to-understand video. Keep up the great work.

Give this man a raise for being so clear and peaceful at the same time and showing clear instructions

thanks mate for showing me first how to fix and then talk about reasons, made me watch the whole video

Thank you! That fixed it! I selected Windows Intel as the first boot option and that seems to have fixed the issue. Well, this specific issue anyway.

I'm so excited! I followed your perfect directions and it didn't work on the first try but the second selection it fixed the problem! I consider myself not very technical minded, but your directions were easy to follow and I appreciate you and your video very much! I think the problem happened after a power outage in our area. Thank you again!

This is the first time that I'm commenting to a tutorial video. You really saved me sir, thank you so much, you just fixed my laptop. At first I'm kinda hisitant to follow your tutorial since I have tried many tutorial here in RU-vid still nothing works, but after deciding to try your methods, my laptop finally worked again. I'm definitely subscribing to your channel.

You are a god damn guardian angel, amazing explaining, gotta subscribe at this moment.

Omg this is the best video I ever seen, I just had this problem now and I was about to cry and calling a technician it was really expensive so I found this on RU-vid and I could resolve my problem with my computer. Can’t believeeeee😮🎉❤ thank you so much for this video. You saved me life. 😂❤

It worked! Thank you for uploading this video This is the first one to make sense!

Thank you so much, straight forward video with great success!

Genuine life saver thanks so much

Thank you. It fixed the problem just by my repeatedly pressing delete after rebooting. It never took me to the bios - just to my log in screen. Thank you.

Thankyou !! u help me alot !!

Thank you! 2 years later this is still helping people! Thanks a lot!

It worked!!! Thank you!

Yup. This worked for me. The night before, I forced shut off the pc with the power button after it would not finish shutting down for a few mins (I have windows installed an an ADATA SU630 SSD, in case anyone is interested). Next day, I tried to boot and I got hit with the problem which led me to this video after getting scared out of my wits by guides in the top Google results which seemed at first to suggest that my drive had died. I had to select something along the lines of my SSD model along with "windows boot manager" for the #1 load option, not the one that just stated the drive model. Hope that helps somebody! Subbed.

OMG THANK YOU SO MUCCHHH IM SO HAPPY TO LEARN THIS AT JUST UNDER 13 YEARS OLD AND ABLE TO FIX IT MYSELF ON FIRST TRYYY :D

Thank u sir I was about to break my pc thank u for helping me 😊

Bro You are the goat!!!!!! I have had this problem for months going unsolved and you fixed it!!! You just earned a sub

Man appreciate it so much i finnaly understood and your the only guy who spoke english clearly 😂

Thank you so much man I really appreciate this you just saved my life you are a very important person thank you ❤

Holy hell THANK YOU!! it actually worked!! Tbh I only followed like the first 2 or 3 steps you said since my pc had a totally different interface than yours and idk what you meant by saying choose which thing to set as your boot option, but I just randomly choose the hard drive option and saved and rest and it actually worked. I was just about to take it to a repair shop and probably get ripped off for such an easy fix. I have a Evoo 15inch gaming laptop btw. Thank you again fam! This is the only problem I ever had with this laptop in almost a year and a half.

Thanks bro...may May Allah s.w.t make things easier for you..thank you

Thank you sir. Got it up and running 💪

Thank you so much this helped me not want to call my brother while he is asleep and help fix the issue!

Yeah, I'm running 1 m.2 1 ssd and 2 HDDs in my pc 😅 It was bound to happen.

hey, getting into bios and loading optimized settings fixed it. However, for some reason, windows boots a lot slower now after doing it. Do you know why?

Thank you. Changed my motherboard, and this happend . Very helpful

Thank you for helping me out.🤙🏿

You know what ? You are a fucking legende bro , thank you soooo much ❤️

I am also having the same issue. Also its been less than a year i bought this pc. Boot driver is an ssd. Now the health of the ssd went to 53%. So do you think this might causing the problem?

Wow just wow 👌 this is an amazing video and channel definitely subbing ❤

Dudei love you man saved my best and most expensive pc I thought I was gonna have to buy another one

so i unpluged and repluged my sata cables then i took out the battery and reset it i open up BIOS and go to boot and i see SATA6G_2: SATAFIRM S11 (476940MB) and i see Disabled what do i do

I had my pc for around 4 years. Then had my windows corrupted and had a guy help fix it for me a few weeks ago. I got my pc today and when I plugged it in everything was fine and installed chrome. Then a few minutes later my mouse frozed and had this screen pop up

TYSM YOU HELPED ME A LOT

For me I just unplugged the power plug that goes into the pc and then re put it in I hope this works for you as well.

Hi, I’m still not sure what to do I was playing with my friend yesterday and my pc suffered from ‘thread stuck in device driver’ multiple times. I’d already checked the drivers multiple times prior, so my friend suggested we downloaded the newest drivers from the official AMD website to sort it out. The first time I tried to download it, I had a ‘critical process died’ bsod, and the second time I fully downloaded and installed it, I got a pop-up saying something along the lines of ‘Windows 10 Process Ended’. I couldn’t do anything so I powered it off. I booted it up again and got this problem. I’ve checked the plugs inside the motherboard, which all seem to be fine. The problem I have is that my pc only has one boot priority, and that one doesn’t work. The only other option is disable, which has the same result. Really not sure where to go from here. Do you have any pointers? Thanks.

Worked, thanks so much.

thank you so much the vid helped me fixing this issue

Never knew i would cry over a broken pc

Hey I have an M.2 that has my windows on it, when I go into the bios it does not register as a selectable drive. I bought the m.2 in 2019 it's a WD blue 1tb. Preceding this happening my PC froze, so I restarted it after several minutes of it not responding to inputs. Is my m.2 dead? EDIT: unusually after hard turning off my PC, (using the power button and not restarting it with the built in button) upon going into bios my M.2 appeared and after selecting it, it has booted up like normal... This concerns me as I am wondering if this means my m.2 is dying or this was just a goof. I'm not sure.

Thx so much u helped me and my problem is EXACTLY the same as ur's and once again... thank you

It worked. Thank you so much 🙂

I'm so fed up at this point, nothing I do seems to work and it just keeps showing me the same screen over and over.

What if my hard drive with my OS isn’t showing up on my Boot Priority List??

Thank you. This worked well. 👏

It works on my PC, thank you so much!

I replaced a faulty hardrive with a new one and now I’m getting this screen. I’ve tried changing the prioritised drive but it keeps happening. Any idea what’s wrong lol?

It opens my computer but a minute later my mouse frozed and pop up a blue screen then restart itself

It works! Thank you for your tips

Big Help. Thanks ❤️

MINE FIXED WHEN I SPAMMED f12 and selected the INVISIBLE boot option with no name lol. Hope this helps someone

This is my first PC build so I might sound stupid, but I haven't plugged in a USB with windows on it yet, would that be a reason for this screen to pop up??? I just want to know if I did something wrong, working on getting the USB and windows sorted should be done soon. But would that solve the issue? No matter what i press, unplug, connect or disconnect it keeps showing me this message..PLEASSSSEEEEE HELP 😭

Great video!

Thank you so much for this video you deserve a sub. 👍
