Ubuntu Suddenly Completely Wipes From My Hard Drive - Windows11/Ubuntu 22.04 Dual Boot

mh flag

I just had a terrible moment with my computer. Just days prior I was working on Ubuntu for my robotics courses, I had reset my hard drive in January to perform a Dual Boot and it worked great. Today I went to boot it up once more and it completely left the building. My partition is still there, but Windows says it is 100% free for storage. The boot option is still there in my BIOS Setup, but when I select it I get a critical error saying "no bootable devices found". All my files are definitely corrupted and gone, right? What can I do to prevent this from happening in the future? How did this happen?

you can boot a live linux and save your date when the filesystem is still there.

Windows does not understand filesystems that are not microsoft made. chek wit a live session if the data is still there and if so do a boot-repair. Maybe Windows did an update and replace your boot but the one from Microsoft

Please copy & paste the pastebin link to the BootInfo summary report ( do not post report), do not run the auto fix till reviewed. Use often updated ppa version over somewhat older ISO with your USB installer or any working install. https://help.ubuntu.com/community/Boot-Repair & https://sourceforge.net/p/boot-repair/home/Home/

Can't address the dual-boot question, but

  1. Always back up your files.

  2. In case you didn't do #1, I've had success using Puppy on a live flash drive to access the "inaccessible" partition. Here is a reference article: https://www.sysprobs.com/puppy-linux-recover-windows-7-files-boot

  3. In case the files are corrupted, you still may be able to recover them through using the photorec application that is included in the testdisk package. See: https://www.digitalocean.com/community/tutorials/photorec-recover-deleted-files-in-linux-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.
