This is first time I am using Linux system. It takes long time to boot and shut down. Also the installation felt really slow. Had to use boot-repair to be able to boot windows again, it added another windows in the grub menu.

    Figure out why it's taking 37 seconds to mount sdb5. Historically, 42 seconds is blindingly fast. A decade ago, 1-2 minutes was common. – user535733 Mar 17 '21 at 15:00
  • Some things to check. https://askubuntu.com/questions/1284302/is-it-possible-to-make-ubuntu-20-04-boot-faster if sda5 is part of issue, does it need chkdsk, if NTFS or fsck if ext4,or have incorrect mount in fstab? – oldfred Mar 17 '21 at 16:02
  • @oldfred its SSD partition with my Windows system, I believe its mounted correctly based on the UUID – Pignon Mar 17 '21 at 16:52
  • its not big deal tho, I intend to use Windows as little as possible – Pignon Mar 17 '21 at 17:03
  • Then it may have fast start up on, which sets hibernation flag preventing Linux NTFS driver from fully seeing it. Note Windows regularly turns fast startup back on, so if issues you may need to turn it off again. http://askubuntu.com/questions/843153/ubuntu-16-showing-windows-10-partitions & https://askubuntu.com/questions/145902/unable-to-mount-windows-ntfs-filesystem-due-to-hibernation – oldfred Mar 17 '21 at 17:33
  • Its W7 so there is no fast boot and I checked BIOS and its also disabled. – Pignon Mar 17 '21 at 17:47

Well of course now that I asked for help, I found a solution... Updating grub seems fixed it. Takes just few secs now.

edit: Actually it fixed only the udisks2.service part of the problem.
