first of all why are you trying to enter safe or recovery mode?

 

your description appears to indicate that the recovery partition is unable to boot or perhaps restore /repair the main os

 

 

you may find it more effective in the long run to simply reinstall the OS doing this will correct a bad recovery partition and also correct any issues with the main OS

Was trying to convert to uefi on legacy machine. Found this since i tried. "https://h30434.www3.hp.com/t5/Business-PCs-Workstations-and-Point-of-Sale-Systems/Updated-quot-Add-N... F9 Machine boots to USB does memory test and hangs.

uefi has no advantages on a boot drive for this older system "Legacy" is the preferred setting as the Bios will not support a drive/partition size over 3.98 TB in size

 

stay with Legacy unless you require a non booting DATA drive that is over 4TB which can be formatted as "GPT"
