Windows 10: Installation stuck at "WIndows can only be installed on GPT disks"

So I have an off brand laptop computer, about 4 years old that had Windows 10 on it. Last week it stopped working and I got the PXE media test faillure screen. After playing around in the BIOS, Aptio Setup Utility, I got as far as a black screen with "Reboot and Select proper boot device" screen. I tried everything, hit every key imaginable, and couldn't get it to recognize anything. I couldn't boot in Safe Mode and I couldn't get back to the Aptio Setup Utility either. Nothing. Finally, I loaded a Create WIndows 10 on a USB drive and plugged it in. After numerous reboots, the laptop recognized it and started marching me through the reinstallation process until I got to the:


Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disks.


I've seen recommendations to hit Shift F10 and reconfigure the hard drive, but doesn't that wipe it clean as well as all of my data? Is there a way to correct the problem at this point without losing data?


Of note, I still have the WIndows Setup screen on my laptop so I can do the F10 thing, but I am not sure I can do anything else with this computer as I couldn't even get into the Aptio Setup Utility before this as well as anything else including Safe Mode.

GPT vs MBR for SSD OS Disk ? (win7 install)

So

I've got a new PC coming and this time it's the first time I will be using UEFI, i have read all the big stuff but I don't have the hardware yet so It's still kind of half baked but I'll do dig deep into it once I start building in the coming days.

I've read the win7 install guides, MS GPT FAQs (not fully yet), etc,

But I wish to know if:

I can use UEFI as an upgraded bios without having to use GPT disk format?

GPT disks can have any sort of partition cloning for full operational OS backup ?

Will GPT format improve performance on SDD or improve reliability in terms of data integrity or error rate?

When isntalling win7 with MBR but using UEFI, will it work normally without needing to uefi-boot the window7 install?


If I cannot backup my OS in a 100% clone that will boot normally when recovered, i will probably not use GPT, that shit is a step backward.

GPT vs MBR for SSD OS Disk ? (win7 install)

If I have UEFI BIOS, I'm going to use GPT. Only reason why I wouldn't is because the drive is shared between new and old computers (MBR has broader compatibility support). I wrote a guide how to install Windows on GPT here:
Installing Windows Vista/7 on a GUID Partition Table

No. Either you install on GPT via EFI boot or you intall MBR via BIOS boot. You can't install Windows and change it later.


Not only does GPT support booting to partitions larger than 2 TB, it also means the computer is booted using EFI which means it has a lot more memory to work with during startup. It should theoretically mean startup is quicker on EFI/GPT than BIOS/MBR.
