To run the live AVG rescue "disk" on USB for Windows 10, how is it made to work with a GPT and UEFI system? (Possible solution listed below.)
I enabled the boot menu so that pressing F12 will display a list to select from. Also, I put everything USB at the top of the boot sequence and Windows and the HDD at the bottom. However, I hadn't realized GPT and UEFI are so different from a BIOS.
Because the USB flash drive isn't compatible with GPT it's not being picked up?
This solution was suggested:
Open the notebook and press quickly F2 to enter the BIOS. Under the MAIN menu, enable the F12 Boot Menu option. Under the BOOT menu, select Legacy boot and press F10 Save & Exit. While the notebook is rebooting, press F2 again to enter the BIOS. Under the BOOT menu, select as your first boot option the USB HDD stick (your USB stick). Press F10 Save & Exit.
Perhaps this will work, but what is the problem that prevents UEFI boot from registering the thumb drive? Because it's using GPT and not an MBR?
I don't want to switch to legacy, but stay with UEFI. The laptop:
