Change from Legacy to UEFI, not booting
Posted: Sun Dec 11, 2022 1:36 am
Lenovo Ideapad
BIOS option for Legacy or UEFI boot
Original Win10 installed in Legacy mode
BIBM installed
Win 10 installed
EFI & reserved partitions created
All worked
Want to change to UEFI
Change BIOS to boot UEFI
Uninstalled BIBM
Installed BUI
changed to GPT
would not boot
ran Fixboot.tbs, twice
still not boot
depending on which I choose, Legacy or UEFI boot in BIOS, I get:
1) BUI start but never continue/freeze
2) if boot with BUI flash, wants to reinstall, process completes, but BUI never seems to stay installed, does not boot into BUI.
3) get BIOS boot options menu, but none of the choices boot.
With BUI not installing I cannot access Bootedit.'
EFI shows the correct OS.
Obviously, I am missing something.
Is this fixable?
