Personal story. I was visiting at my FIL's home. He was out of town and let us stay there for a couple nights when we were traveling. I didn't have password to his windows 10 UEFI computer. So, I changed it to Legacy/CSM and put in my Linux Mint 17 DVD and booted to it instead.
I forgot to remove it. When he got home, he called and was all excited about seeing Linux instead of his Windows. I walked him through the steps on setting BIOS back to UEFI and rebooting. His world was restored, LOL.
While trying to fix a boot error (0xc0000034) on my laptop I accidentally changed my computer's BIOS from UEFI to Legacy, is there a way to change it back?
The computer is clean so it doesn't matter if it's a method that causes loss of data. I have a bootable USB with windows 10 (maybe
on it. At some point I got into the menu for this, but must of the times I just get straight to the BIOS. And when I got to the menu for installing windows, I got the error message "windows cannot be installed on this disk. The selected disk is of the GPT partition style." so I couldn't get past from there anyway
The computer is an MSI GE70 2QE
I can't find a way here to post photos from my iphone (and can't use the computer), but here is what it says on the startup screen of the BIOS. The only options I have from here is either "Delete RAID volume" or "Reset Disks to Non-RAID" (none of which I know what it means)
Physical devices:
ID. Device model. TYPE/STATUS(Vol Id)
0. PLEXTOR PX-256M6. Member Disk (0)
1. PLEXTOR PX-256M6. Error Occurred (0)
4. HGST HTS721010A9. Non-RAID Disk
I know I ****** up and should have done more research before tweaking with this, but the damage is done so I greatly appreciate any help
