I'm pulling my hair out with this one.
I've got a HP TouchSmart 320 PC that I upgraded to Windows 10 mid last year from Windows 7. Bought the PC with W7 installed. Have had it in a box for months while I was overseas and turned it on a few days ago to find the keyboard scrambled. Stupidly, rather than buy a new keyboard, I decided to do a reset of Windows 10.
My problem now is a reboot loop with Error: Inaccessible_Boot_Drive. I couldn't access BIOS (it says for my PC to hit ESC, but I've tried that as well as all the F1-12 keys, etc). I've downloaded the Windows 10 iso and have successfully got it onto a usb correctly with my mac using boot camp. Everything goes well as it enters Windows set up when I plug it in but the problem now is that my 4 Disk 0 partitions (System, etc) have this error:
Windows cannot be installed to this disk. the selected disk has an MBR partition table. On EFI system, Windows can only be installed to GPT disks.
I've been reading further into this and it looks like theres some (bad?) suggestions saying to delete these partitions and make my own new ones, but people have also said thats not a wise idea. Other instructions say this:
1. Follow these steps if the hard disk volume size is less than 2.19 TB: Temporarily disable the EFI Boot Sources setting in the BIOS: Restart the computer, and then press F10 to enter the BIOS. Navigate to Storage > Boot Order , and then disable the EFI Boot Sources . Select File > Save Changes > Exit .
2. Install the Windows operating system.
3. Enable the EFI Boot Sources setting in the BIOS: Restart the computer, and then press F10 to enter the BIOS. Navigate to Storage > Boot Order , and then enable the EFI Boot Sources . Select File > Save Changes > Exit . Follow these steps if the hard disk volume size is greater than 2.19 TB: Follow the steps in the Microsoft document titled "How to Configure UEFI/GPT-Based Hard Drive Partitions" (in English) to create a GPT partition
But, I'm back to square one because I can't load the BIOS menu no matter what I press. With the usb in, it just goes to windows set up. Without it, I'm stuck in the boot loop.
I would be so grateful for any suggestions! I can follow instructions but I'm no IT whiz. Also - if its relevant, I only have access to a Mac for now. Thank you!
EDIT: My scrambled keyboard was only affected on the right third (approx). So I don't think thats the problem when I'm trying to enter BIOS as I checked before I reset the computer and ESC, all the F keys, spacebar and most of the letters were ok.
