don't laugh but i succeeded in totally crashing my computer. and no: i am not 12 years old.
Had a SSD and dual boot Windows 8 + Ubuntu (GRUB2) worked nicely. installed KALI instead of Ubuntu. Grub just landed in its
GRUB> _ shell
In BIOS (UEFI?) windows was in entries for boot overrides and i could boot, but linux not.
Tried to take my kali-installation-and-live-linux-usb stick to boot into the live-system, worked. Did lots of stupid stuff. I mean REALLY stupid stuff with parted, gparted, chroot, tried everything, added boot-flags, removed boot-flags, totally wiped it... ended up having a total corrupted partition table, my windows + linux partition are still there and ok, i can see them in EFI, but if i select them to boot nothing happens.
long story short: ended up installing rEFInd via my live linux, worked, but no linux nor windows entries are there,
strange thing: if i use rEFInd-live stick it finds my linux and boots it (and windows, but only recovery mode, not normal boot :-( )
any plans to recover this desaster without wiping the complete SSD? partition entires? boot flags?
Greetings
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
It sounds like you may have damaged your partition table and/or files on the ESP. I'd need to see detailed information (as produced by Boot Info Script, before offering specific suggestions, beyond this: It may be time to extract whatever personal data you can, wipe the disk clean, and re-install. Recovery in a less drastic way may be possible, but it will require effort that would likely equal that of a complete restore.
Oh, and what you see in the firmware as boot options are not partitions; those are pointers to EFI boot loader files on the ESP, stored in NVRAM. Partitions are disk structures. You could legitimately have a hundred NVRAM boot entries and just a couple of partitions; or a hundred partitions and just one NVRAM boot entry. The two are mostly unrelated.
