Hi,
new here and with Linux in general, seeking help with booting. Suddenly I was dropped into a grub rescue prompt when turning the computer on. After googleing, I made a live USB with boot repair. Booting took about an hour, and repair got stuck at a part where it said remove kernels and reupload last kernel.
I don't know if I have SW or HW RAID or not.
I have the boot info pasted in. Any advice is appreciated.

the same hard drive for core.img. core.img is at this location and looks
for (,msdos1)/grub.
=> Syslinux MBR (4.04 and higher) is installed in the MBR of /dev/sdb.

=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to enable-raid enable-lvm) and reinstall the grub2 of mapper/ubuntu--vg-root into the MBR of sda, using the following options: kernel-purge
Additional repair would be performed: unhide-bootmenu-10s
=================== User settings
The settings chosen by the user will not act on the boot.
new here and with Linux in general, seeking help with booting. Suddenly I was dropped into a grub rescue prompt when turning the computer on. After googleing, I made a live USB with boot repair. Booting took about an hour, and repair got stuck at a part where it said remove kernels and reupload last kernel.
I don't know if I have SW or HW RAID or not.
I have the boot info pasted in. Any advice is appreciated.

============================= Boot Info Summary: ===============================
=> Grub2 (v2.00) is installed in the MBR of /dev/sda and looks at sector 1 of
the same hard drive for core.img. core.img is at this location and looks
for (,msdos1)/grub.
=> Syslinux MBR (4.04 and higher) is installed in the MBR of /dev/sdb.

=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to enable-raid enable-lvm) and reinstall the grub2 of mapper/ubuntu--vg-root into the MBR of sda, using the following options: kernel-purge
Additional repair would be performed: unhide-bootmenu-10s
=================== User settings
The settings chosen by the user will not act on the boot.
