Grub says Invalid Partition Table, yet still boots?

AtheistSpacePony · 2016-04-30 16:15:26

Whenever I boot into my Arch Linux install, I get the "invalid partition table" msg, but usually when I get this msg, previous distros fail to boot, yet somehow it's different this time... I used msdos partition format... should this error msg be anything to worry about? Kinda new to full on arch... Freshly migrated from manjaro net...

Welcome to Arch Linux. Is this a BIOS system with an MBR partitioned disk, or is this an EFI system with a GPT partitioned disk?

AtheistSpacePony · 2016-04-30 16:25:22

Thank you. :3 It's bios with MBR.

Do you have multiple disk drives? Or a disk drive like device plugged into a USB port?
When do you get the message? Before your bootloader, or does Grub generate it before it displays the boot menu? or after you select on OS and the kernel is loaded ?

It's just one disk drive... had a usb disk plugged but unplugged it. It goes like this...

1) Power on the computer
2) Invalid Partition table
3) Grub loading, welcome to grub
4) Lists my options...
5) Boots into Arch Linux

Okay, let's see the output of sudo fdisk -l

This is it right here...

So, what is /dev/sdb? I thought we had but one disk

AtheistSpacePony · 2016-05-01 01:18:18

Oh, that's because prior to running sudo fdisk -l, I inserted the USB drive. I had to grab some stuff from there.

R00KIE · 2016-05-01 13:36:46

I don't see anything wrong with that partition table and fdisk doesn't seem to find anything wrong either. I would suspect that warning/error might come from the bios and not grub.

The only thing I see that is not common is that you are leaving unused almost 1GB at the beginning of the disk.
