[Solved] GRUB> (I need help)

[Schro79]

Hello,

I have a problem, I had an old version of virtualbox, I left the new update and I accepted (version 5.1.28 ). After I wanted to open my virtual machine and show this:

Code: Select all

GNU GRUB version 0.97 (639K lower / 3668928K upper memory)

[Minimal BASH-like line editing is supported. For the fisrt word, TAB lists possible command completions. Anywhere eslse TAB lists the possible completions of a device/filename]

grub>

I used linux but I'm really new to this and I do not know what to do. I have important files in the virtual machine and I want to log in to continue working on my projects. Someone who can help me solve this? (sorry if my english is not excellent)

This question does not concern "Windows Hosts" - please choose a sensible forum to post in next time. Moving this one to "Linux Guests".

Please provide a VM log file. With the VM fully shut down, right click it in the GUI. Select "Show Log" and save "VBox.log" (ONLY) to a zip file. Attach the zip here.

ok, thanks for the advice

I attached the zip of VBox.log

If you need any more information please communicate

Ok. First of all you've assigned too much RAM to the VM. I would reduce the allocation to 2GB.

00:00:05.512343 Host RAM: 8107MB (7.9GB) total, 3204MB (3.1GB) available
..
00:00:06.192209 RamSize <integer> = 0x0000000100000000 (4 294 967 296, 4 096 MB, 4 GB)

Also, you have a dual core host and assigned both cores to the VM, leaving none for the exclusive use of the host. This means that the VM has the potential to drag down the host. However you had better leave this for now until it becomes certain that its a problem.

Meanwhile, graphics RAM is far too low for any guest that uses a GUI. I'd increase to 64MB.

00:00:06.192478 VRamSize <integer> = 0x0000000001000000 (16 777 216, 16 MB)

Finally, we get to the boot section.

00:00:10.596638 VMMDev: Guest Log: BIOS: Boot : bseqnr=1, bootseq=3142
00:00:10.624928 VMMDev: Guest Log: BIOS: Booting from Hard Disk...

00:24:42.036205 Changing the VM state from 'RUNNING' to 'SUSPENDING'

This looks like a normal boot, and I note that the VM ran for 24 minutes after that, before being shut down by yourself. I'd say that you have a GRUB problem, not a VirtualBox problem (apart from all the problems described above). So if you fix the problems described above and still can't boot then I would ask on a Linux or GRUB forum. What you may have to do is mount the disk in another VM, and access the grub script to fix what's wrong with it. Typically what's wrong with it, if it ever worked and hasn't been corrupted, is that you cloned a drive, which changes the ID which GRUB is using to identify the boot drive.

Hello,
I used the configuration that you recommended and now it goes well.
Continued with the problem, so I looked in forums about linux grub and fix it with the help of several posts with the same error.

Thank you so much for the help and advices!!
