I installed Ubuntu alongside with the Win7, rebooted PC, removed flash with installation files as the guide said and recieved a GNU GRUB screen with several options: Try or Install Ubuntu, Ubuntu(safe graphics), OEM install(for manufacturers), Test memory.

Why there is no option to choose Win7 and non-safe graphics Ubuntu and how shoul I deal with those issues?

  • If you are using 22.04, have you enabled os-prober by setting GRUB_DISABLE_OS_PROBER=false as detailed in this answer? – mchid Aug 12 '22 at 02:11
  • Otherwise, windows may be in a hibernated state and you are supposed to have windows in a fully shut down state when installing Ubuntu. For one thing, you should disable the quick boot feature in BIOS if one exists. – mchid Aug 12 '22 at 02:21
  • If windows is in a hibernated state, you should be able to see the partition when you run lsblk or blkid and it should show up as an NTFS partition. If *and only if* the NTFS partition does show up and fixing the os-prober problem does not solve the issue, then, *as a last resort, you can use ntfsfix to fix the hibernated windows partition as described in this particular answer. It should be noted that this is possibly unsafe and could corrupt some Windows data so this should be a last resort.* – mchid Aug 12 '22 at 02:26
  • If the NTFS partition does not show when you run lsblk or blkid then please edit your question and post the output of those commands. – mchid Aug 12 '22 at 02:27
  • You haven't provided any Ubuntu product/release details; but the Try/Install choice you describe implies to me it wasn't installed at all as that try/install question exists only on uninstalled media. You also said rebooted PC then removed media; thus implying you potentially rebooted the installation media as it hadn't been removed in time. If you boot again does it occur? – guiverc Aug 12 '22 at 03:18
  • Does this answer your question? GRUB does not detect Windows – karel Aug 12 '22 at 15:04

    If you're seeing "Try..." or "Install..." options then you din't remove the installation media. It's that simple. – ChanganAuto Aug 12 '22 at 17:37
