Can I use virtualization without grub crashes? Why does grub crashes after enabling BIOS virtualization?

us flag

I have a dual Ubuntu/Windows PC. I installed VirtualBox on Windows OS but it didn't work. I read that I had to enable virtualization on the BIOS, so I did it. After that, grub didn't start. I tried to restore grub with supergrub2 without success. Tried with a live CD without success. Tried to reinstall Ubuntu 21.10... I couldn't.

So I went to BIOS to disable virtualization, and grub started correctly.

It's a problem with the firmware (UEFI). Updating it should be your first troubleshooting step. Even without the update you should perhaps check what other changes you be inadvertently making and/or whether the boot order isn't somehow changed by enabling virtualization (it shouldn't but you must check anyway and adjust accordingly). This has nothing to do with Ubuntu.

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.
