Laptop doesn't boot after Windows update

[Earl Talatala]

After updating my laptop to the latest software, my laptop restarted and it keeps taking me to the BIOS, where the boot loops happen. Disable features and enabling some manage to escape the BIOS boot loop, but BSOD greets me in the end :( I tried contacting ASUS regarding the issue and the only solution they gave me is to bring the unit to the nearest service center, where they probably (and most likely) format my HDD for good. Any help? Thank you so much!

Can you create on another system a bootable windows usb drive? Then you could try the repair option and see if it helps

Press F8 when the computer boots and see if you can get into Safe Mode. From there, you can try to uninstall the updates that were applied. You can also open System Restore within Safe Mode and see if you can restore to an earlier restore point. Pending on the type of update, Windows may have automatically created a restore point before the update was applied.

Three possibilities come to mind:

1) UEFI/Legacy mode switched , this will make the OS drive disappear and give an instant BSOD

2) iRST/AHCI switched, this will prevent windows from booting forever, you can work around it in the bios, boot into safe boot once you get it to boot, and then switch it to where it should be, boot into safe boot again an unselect safeboot

3) Drive is borked/drive firmware is borked.

 

With SSD's when they wear out, they just flat out stop working. Take a picture of the BSOD with a cameraphone so you can get the exact code. If you see something like "BCD" that's probably issue #2, or it the Legacy CSM's were turned off.

 

Anything else where the OS doesn't get to a point where you can recover it tends to be CPU/RAM failure and you would want to run diagnostics before trying to boot the OS.

Problem is I don't have another system in which I can create a bootable USB drive

Getting into Safe Mode is the most common answer by all, but I can't do anything besides watching my laptop infinitely boot into just the BIOS, or showing BSOD whenever I try to change the boot priority. Even if I press F8, it just straight bring me to the BIOS and repeat, again...

Edit: pressing F8 while booting up shows a black screen with a blinking cursor...
