My computer is a HP Pavillion g4 notebook PC I made some modifications like installing an 120GB SSD drive and replacing the CD drive by a 120GB HDD drive and expanding the RAM from 4GB to 8GB.
When I installed Ubuntu I usually used the "erase disk and install Ubuntu" option and always worked for me until the past month when I tried to boot my PC and it showed a error and when I went back to grub the boot menu was glitched so I thought it needed a reinstall, but when I installed Ubuntu vía "Erase disk and install Ubuntu" after I rebooted it said unable to read and write outside of hd0 and error: you need to load the kernel first.
I tried some solutions show here: What to do when I get an "attempt to read or write outside of disk 'hd0'" error and Boot Repair does not solve the problem? Including Boot-Repair.
The first one:
grub rescue > ls
(hd0) (hd0, msdos9)
grub rescue > ls (hd0,msdos9)/
grub rescue > ls (hd0,msdos8)/
grub rescue > ls (hd0,msdos5)/ # suppose this is root and bootloader of Linux
grub rescue > ls (hd0,msdos5)/
grub rescue > set root=(hd0,msdos5)
grub rescue > set prefix=(hd0,msdos5)/boot/grub
grub rescue > insmod normal
grub rescue > normal
My partitions were different, but I managed to locate them using the ls command.
Additions 19/11/2024: The partitions were GPT, so it may support UEFI I think, but I'm still unable to boot.
Another solution I tried that partially worked is creating a 1024MB ext4 partition located on /boot which works but...
- The boot time is too long seriously I can turn the PC, make the breakfast, watch some videos, and its still booting with a black screen it delays too much to show the Ubuntu plymouth screen, sometimes this ends in a timeout or kernel panic.
- Break some tools like haxeflixel (I think) before this issue I didn't have problems with that took but when I boot using the
/bootpartition. It works, but with a lot of errors, one of them being "segmentation fault".
It also happen when I install other Ubuntu-based distros like Linux Mint or Elementary OS, I always install Ubuntu on the SSD, my PC does not support GPT so I have to use mbr. I made the boot drive from Windows using Rufus.
Edit 19/11/2024: I managed to get a pastebin when I tried https://paste.ubuntu.com/p/hw3vFSmpKs/
============================= Boot Repair Summary ==============================
Recommended repair: ____________________________________________________________
The default repair of the Boot-Repair utility will purge (in order to reset grubenv) and reinstall the grub2 of
sda2 into the MBR of sda.
Grub-efi will not be selected by default because no ESP detected.
Additional repair will be performed: unhide-bootmenu-10s
chroot /mnt/boot-sav/sda2 apt-get -y update
Running in chroot, ignoring command 'start'
Purge the GRUB of /dev/sda2

====================== Reinstall the grub-pc of /dev/sda2 ======================
chroot /mnt/boot-sav/sda2 grub-install --version
grub-install (GRUB) 2.12-1ubuntu7
==> Reinstall the GRUB of /dev/sda2 into the MBR of /dev/sda
chroot /mnt/boot-sav/sda2 grub-install /dev/sda

Boot successfully repaired.
You can now reboot your computer.
Please do not forget to make your BIOS boot on sda (ATA HP SSD S600 120G) disk!
The boot files of [sda2 (end>100GB)] are far from the start of the disk. Your BIOS may not detect them. You may want to retry after creating a /boot partition (EXT4, >200MB, start of the disk). This can be performed via tools such as gParted. Then select this partition via the [Separate /boot partition:] option of [Boot Repair]. (https://help.ubuntu.com/community/BootPartition)
