After a necessairy boot repair, the kernel load time is significantly longer than normal: 34s. http://paste.ubuntu.com/p/s45GGcf22B I don't know how to fix that.

about: Long kernel load time the Intel Speed Step, on or off gave me both 34s for the kernel to load.

I don't understand this solution well: Is it normal for Ubuntu to take a long time to shut down after running the boot-repair program?

My grub menu seems to be on my Windows SSD and my Ubuntu on an other SSD.

I had to repair the boot since I accidently pulled out a data cable of one of my SSD drives. Luckily, I have access to my Windows and my Ubuntu.

Here is my startup script in the Grub Customizer for Ubuntu, causing the slow start:

Here is the script I found in the Grub customizer to launch my Ubuntu:

gfxmode $linux_gfx_mode
insmod gzio
if [ x$grub_platform = xxen ]; then insmod xzio; insmod lzopio; fi
insmod part_msdos
insmod ext2
set root='hd1,msdos1'
if [ x$feature_platform_search_hint = xy ]; then
  search --no-floppy --fs-uuid --set=root --hint-bios=hd1,msdos1 --hint-efi=hd1,msdos1 --hint-baremetal=ahci1,msdos1  c1d84984-8159-4a32-bf22-a30e1d0f33fe
  search --no-floppy --fs-uuid --set=root c1d84984-8159-4a32-bf22-a30e1d0f33fe
        linux   /boot/vmlinuz-4.15.0-128-generic root=UUID=c1d84984-8159-4a32-bf22-a30e1d0f33fe ro  quiet splash $vt_handoff

  • I don't see any need to check a full filecheck because there was no data connection to the disconnected partition. I just need to know how to launch. My Ubuntu to launch is at: /dev/sdb1.

  • Do you have the old BIOS/MBR configuration, not new UEFI with gpt partitioning? Unless old system better to use UEFI/gpt. Grub Customizer replaces grub scripts with its own proxy scripts. Lets see details, use ppa version with your live installer (2nd option) or any working install, not Boot-Repair ISO: Please copy & paste the pastebin link to the Boot-info summary report ( do not post report), do not run the auto fix till reviewed. help.ubuntu.com/community/Boot-Repair

  • Some more info: systemd-analyze time Startup finished in 6.033s (firmware) + 5.200s (loader) + 34.282s (kernel) + 4.449s (userspace) = 49.966s graphical.target reached after 4.262s in userspace grub-install (GRUB) 2.02-2ubuntu8.20

I finally found the solution: Boot hangs for 30 seconds at "Begin: Running /scripts/local-premount" THe system searched for a swap file, which I don't have. I don't need a swap for my 8 GB!
