Linux not booting

**DaCalebMan** · 10-09-2009

I installed a new usplash this morning called Ubuntu-smooth (an identical version of the original usplash, but with a smooth non -pausing progress bar.) Anyway, after an accidental hibernate (I missed the reboot button) I noticed that the usplash wouldn't display at all! Only text! However during text-mode, I glimpsed what Ubuntu was doing, it tried to unmount my usb flash-drive (source of usplash) but [FAILED] to do so, so after turning the PC back on again, I went to startup manager, looked for the usplash problem, couldn't find it, accused the boot-loader menu, disabled it and shutdown.

Now, whenever I turn the computer on I get a blinking underscore, or if I insert the flash-disk, this:

Code:

 (some random combination of numbers) Assuming drive-cache. Writing...

Then does NOTHING. What do I do?!

Hi DaCalebMan
Look at [sdc] Assuming drive cache: write thru - Ubuntu Forums . I think it is similar to your problem.
Cheers....

It is quite similar,

but in my case, it happens as soon as I boot, not when I try to write to it.
I'm booting off the live CD, and I am able to do anything with the flash. I've even taken all the data off it and put it in a spare internal drive. However when my computer is off, I take out the flash-drive, then boot, I get stuck at that blinking cursor, you know, the one means it's checking for operating systems elsewhere first?

I really don't know what to do about this one.

Hello! Fire up your favorite LiveCd and open a terminal window please, post the output of these commands. Hopefully we can see something going on here.

Code:

sudo mkdir /mnt/ubuntu

Code:

sudo mount /dev/sda1 /mnt/ubuntu/

The above code assumes you are using /dev/sda1, you may need to change this according to your needs.

Code:

sudo fdisk -l

The above code is a lowercase L, not a 1, which is a common mistake.

Code:

sudo cat /mnt/ubuntu/etc/fstab

Code:

sudo tail -100 /mnt/ubuntu/var/log/messages

Here's the Results:

(Sorry, I had to attach it instead of copy and paste, to prevent windows from sabotaging it)

P.S, do you think formatting the flash drive might help?

Thanks, ~Caleb

Are you booting strictly from the USB device or are you having problems with both devices? I was under the impression that you couldn't boot from the HDD.
Formatting the Flash drive will destroy everything on it, you'll need to rebuild what ever you currently have on it.

Oh, sorry to confuse you. The problem is I cannot boot from the hard drive, and the USB flash drive is being considered a drive cache by Ubuntu. I have already cleared all my files off the flash, and I was hoping formatting the drive, would make Ubuntu re-identify it. (I could do this on a Win-PC)

Thanks!
