Some of My Grub Menu Options Magically Disappeared

**arius88** · 2 Weeks Ago

Hi helpful humans!

My computer is set up as a dual-boot system with Windows 7 on one partition, and Lubuntu on the other.
I mostly just use the Lubuntu system, but today, for the first time in a while, I wanted to use Windows.

Previously the Grub Menu had contained several options. I don't have them memorized but it was something like this:

Ubuntu
Ubuntu Advanced Options or Something
Mem Test
Mem Test
Windows 7 sda or sdb or whatever (Wrong, does not load windows)
Windows 7 sdsomethingelse (Correct)

The grub menu pops up every day when I boot my computer, but the first four options are the only ones that display, and then you have to scroll down to see the Windows 7 options, which I hadn't done in a while. I'm not sure how long it's been, probably months since I had any desire to use Windows. I mention this because I'm not sure how long my issue has been a thing. I suspect that the grub updated itself or something, and screwed itself up somehow. I certainly don't recall making any changes to it.

Today, I tried to scroll down the menu, and there IS no down. The options to boot Windows 7 are just... GONE. They no longer exist in the grub menu.
What gives? And how do I fix it?

Is there a way to access the Windows Partition without it?

Thanks,
Arius

Windows 7??
That was normally old BIOS/MBR configuration. Systems since 2012 are UEFI with gpt partitioning.
With old BIOS/MBR installs you only have one MBR (per drive).
So if you have two drives, do you have Windows boot loader in one drive & grub in other to allow boot of other system from BIOS?

Please copy & paste the pastebin link to the BootInfo summary report ( do not post report), do not run the auto fix till reviewed. Use often updated ppa version with your USB installer or any working install over somewhat older ISO.

With newer UEFI systems, all systems have boot files in an ESP - efi system partition and can then be directly booted from UEFI boot menu. Windows often breaks grub boot of Windows, so that configuration is required.

As a test, open a terminal and run

Code:

sudo update-grub

Watch the printout. Does it show Windows 7 as a boot option?

The simplest thing to attempt to repair this problem is the update -grub suggestion above and if that does not succeed, get boot repair as suggested in post 2 and make sure NOT to try to do a repair. I have a number of questions but they should all be answered with the boot repair output.

Ah. I just ran the boot repair and came back to find the update-grub messages. So I'll try that, but in the meantime here's the pastebin generated by boot-repair:

Based on my reading of it, running boot-repair should fix my issue. But I'll try updating the grub and report back first.

Thanks for the responses! BRB.
