Hi,
I have a computer running ubuntu 14.04 that I was using media centre, and right now it's unable to boot and I'm worried the disk might be damaged. I'm a novice user and could really use some...

Thanks for your reply, that worked!

I'd read about using chroot, but hadn't understood how to set it up properly. I ran update-burg, and it booted it up fine. I guess this is because...

I recently installed updates from update-manager and now when I try to boot into ubuntu, I get this message "Alert /dev/disk/by-uuid=[XXX] does not exist. Dropping to a shell.". I am running Ubuntu...

Well, I created a new partition table, restored the partitions and I've managed to salvage all of my files.

Thanks to everyone who responded

I actually tried to repair the disk using Disk Utility again, but this time I noticed the problem it detected was with the volume's bitmap.

Thanks for your response.

I've emailed you the output of that command. In Disk Utility, I had previously tried to disable journaling and to "repair" one of the paritions. Both attemps failed. I...

Also, parted lists the partition table of the drive as "msdos" but Disk Utility says it's Apple. If I use mklabel, just I make it mac or msdos?

I ran testdisk on this drive and it managed to identify both lost partitions and their start and end sectors. Only it couldn't write the partitions and gave this message : "Function write_part_mac...

"sudo diskutil list" :

According to "parted /dev/sdb print" the partition table is msdos, but it was created using disk utility and hfs+. Does that make sense?

"sudo gdisk -l /dev/sdb" :

gdisk: /lib/libuuid.so.1: no version information available (required by gdisk)
GPT fdisk (gdisk) version 0.6.13

Partition table scan:

Disk utility lists them both as hfs+, one journaled and one not. Would I really need to reformat the drive? I was able to read and write to it previously with Ubuntu. Also the output of "parted...

I'm about to make a clean install of my dual-booting Ubuntu and Windows 7 system, so I made some backups to an external hard drive which has two partitions, one hfs+(journaled) and one hfs+. I would...

In post #23 I was trying to boot with acpi disabled because I'd read it could help, but this did not make a difference because I didn't know that acpi was already disabled in the BIOS. The problem...

It's fixed. System monitor now shows all four cores. The problem was that apic wasn't disabled in the kernel line, but it was in the BIOS setup. I'd already checked the BIOS to make sure all cores...

I'll probably try booting into a 64-bit LiveCD later today. Would compiling a new kernel possibly fix this issue?

Would a fresh install fix the problem? Could installing 64 bit ubuntu or booting into a LiveCD help?


Is there a way to reinstall the kernel, or something along those lines?

The output of "sudo lshw | bzip2 -c > lshw.bz2" is attached to this post.

Does ubuntu 8.10 use the 386 or 686 kernel? I've read that 686 is better for Intel processors. Is this true?

I tried booting with noapic and then with acpi=off at the end of the kernel line, but it did not make a difference.

This is the output of dmesg | grep -i cpu:
[ 0.000000] Initializing cgroup...

I tried booting from an 8.04 LiveCD but system monitor still didn't recognize all 4 cores. Could booting into a more recent LiveCD help?

I've seen posts where booting with acpi off helped. Should...
