Can not enable boot from hard disks in BIOS

cn flag

Please help me!

I have just run the mbr2gpt.exe /convert command and now my PC can not boot from all the hard disks althought the BIOS can recognize them. In BIOS, BOOT section, when enter each line of the corresponding hard disk, the corresponding note is DISABLE without other option to enable it as usual.

I tried to restore all my disks to MBR, re-install Window 10, update the BIOS (with ROM file), to restore my BIOS to default ... but all methods do not give any change. Now my PC can only boot from a boot disk and I can not enter the operation system..

Please help me! Many thanks in advance!

Please refer https://askubuntu.com/help/on-topic, Ubuntu and official *flavors* of Ubuntu (https://ubuntu.com/download/flavours) are on-topic on this site. The on-topic link provides alternate SE sites for non-Ubuntu OSes. `mbr2gpt.exe` is not a valid Ubuntu command, so why ask here?

Do you have a FAT32 EFI-system-partition with a specific UUID and a bootloader installed on that specific partition?

Before you converted back, you probably just needed to reinstall both Windows boot loader & Ubuntu boot loader in UEFI boot mode. And that does need ESP - efi system partition as suggested above by paladin. And if totally reinstalling, why not convert drive to gpt & install in UEFI boot mode. Note conversion during install will probably erase drive.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
