Hi, I have been fighting with this for several hours now and I feel pretty lost. I don't even know how to describe it in short.
So I am describing all I have managed to find out in the hope that someone will have some idea or suggestion. I have a Lenovo ideapad on which I had Windows 10 and I think Ubuntu (about 8 month ago, so probably 18.10 or 19.04). As I recall I installed them dual boot, but as it was not my computer only the Windows was used. The built-in video camera did not work so today, following the instruction of the automated hardware check of Lenovo I ran the BIOS upgrade program. Since then I cannot boot the system, it does not even seem to recognize the harddisk properly. Before the flash I looked at the Boot section in the BIOS and as I recall it had 3 interesting options ubuntu something Windows (I don't recall the exact name) ATA HDD: SAMSUNG .... and a few about USD HDD/USE CD etc. now when I enter the BIOS I don't see the one that had Windows in its name. This seems like a problem :( ------------------------------------------------------------ If I set the "ATA HDD" as the first on the boot order I see "System bootloader not found" and then it reboots automatically. It also seems to set the boot-order back to 1. ubuntu 2. ATA HDD: SAMSUNG .... ... When I boot now it automatically gets into the grub cli: grub> grub> ls (hd0) (hd0,gpt5) (hd0,gpt4) (hd0,gpt3) (hd0,gpt2) (hd0,gpt1) grub> ls (hd0) Filesystem is unknown same with all the others except grub> ls (hd0,gpt2) Filesystem is fat. grub> ls (hd0,gpt2)/ efi/ System Volume Information/ This is the same as grub> ls / I have no idea what to do with this. I guess I need to find the /boot somewhere, but so far I could not find it. Any ideas here? --------------------------------------------------------------------- Booting from disk on key: I found a disk on key with Ubuntu 18.10 on it. After plugging in and changing the boot order in the BIOS I managed to boot from it. I could even connect to the wifi, but I don't know how to access the harddisk of the computer. sudo lsblk shows me NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT loop0 7:0 0 1.8G 1 loop /rofs loop1 7:1 0 87.9M 1 loop /snap/core/5662 loop2 7:2 0 140.9M 1 loop /snap/gnome-3-26-1604/70 loop3 7:3 0 2.3M 1 loop /snap/gnome-calculator/238 loop4 7:4 0 13M 1 loop /snap/gnome-characters/124 loop5 7:5 0 14.5M 1 loop /snap/gnome-logs/45 loop6 7:6 0 3.7M 1 loop /snap/gnome-system-monitor/57 loop7 7:7 0 42.1M 1 loop /snap/gtk-common-themes/701 sda 8:0 1 14.3G 0 disk /cdrom ----sda1 8:1 1 1.9G 0 part ----sda2 8:2 1 2.4M 0 part where sda is the disk on key. At this point I was wondering how could I access the HD when running Ubuntu from USB. any pointers, ideas are welcome Gabor
