I cannot install Kubuntu (or Unbuntu) 10.4 on my husband's computer. I have spent 5 hours on this and cannot get anywhere. I am deeply frustrated. The iso I burned to CD is good (works on 2 other computers). His computer will not boot from USB, no matter what I do to the drive order in BIOS. After loading the blue screen with the Kubuntu logo on it (and the blue-white dots), the screen changes to black and shows the following text:
BusyBox v1.13.3 (Ubuntu 1:1.13.3-1ubuntu11) built-in shell (ash) (initrafs) Unable to find a medium containing a live file system.
He really needs to get rid of WinXP. Kubuntu is what I have on my computer (and love it!). Here is some info about his computer:

I am running the latest suse release downloaded directly from their website. I ran the installation after buring the dvd and everything seemed to be working fine. after the installation i ran updates and used it for a little bit. When i shut it down that night and went to restart it I got an error that stated the OS wasnt there. I then went through the installation and everything and it retained the information from the installation before (web history etc.) but for some reason every time I reboot or shut it down the system is not able to read the startup information from the hard drive and will not come on without me re installing it.

It seems (really not sure what happened...) that my hp dv4 laptop failed to hibernate. when I came back, the fan was still spinning, the 'on' indicator was lit, opened the screen to find a black screen with a white cursor blinking. the reboot halted when it failed to mount /dev, /sys and /proc. it gives me a comand shell named 'ash'. typing /init gives similar errors reporting that the device is busy. different from the first error that there 'is no such file...'
booting off a live CD, the disk utility can't mount or otherwise manipulate the drive. the error comes back (again) that the device is busy. I'm looking for some way to get at the hard disk to either recover it or format the thing and start over. (backups are wonderful.) However, using the livecd to format fails as well.

I Am Having Problem With My JFS Partition On Which Ubuntu Is Installed. It Is Not Mounting. The Bootscreen Says There Is Serious Problem With Mounting The Partition And It Does Not Load Linux. I Tried jfs_fsck -p and -a But With No Success. I Also Tried Checking For Errors Using GParted.
The Logscreen Said logredo failed and unrecoverable error reading M from /dev/sda5/ CANNOT CONTINUE. Is There Any Way I Can Repair This Or Atleast Get My Data Back?
Upon trying to boot Windows I got through the GRUB startup selections and then i get stuck at a black screen displaying "Starting Up. . ." That would be no problem, I just boot ubuntu instead and mount the partition to access the programs I'm looking for. Now I get an interesting error message:
"Error mounting: mount exited with exit code 13: ntfs_mst_post_read_fixup: magic: 0x00150000 size: 4096 usa_ofs: 0 usa_count: 1040: Invalid argument Actual VCN (0x15000011d92501) of index buffer is different from expected VCN (0x1). Failed to mount '/dev/sda1': Input/output error NTFS is either inconsistent, or there is a hardware fault, or it's a SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows then reboot into Windows twice. The usage of the /f parameter is very important! If the device is a SoftRAID/FakeRAID then first activate it and mount a different device under the /dev/mapper/ directory, (e.g. /dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation for more details."
I would run chkdsk in windows if I could, but that's my problem in the first place.
I have a problem with my laptop. I have Ubuntu 10.04 Lucid Lynx installed.

Everything was working great with my FC12 box. I think the Fedora Gods must be punishing me as I had recently downloaded an image for another distro, but was only trying to install it to usb and play with it on another computer!
Then I tried to boot and I got an error message:

Boot has failed, sleeping forever. I obviously don't understand the boot process well enough to fix this problem, so I'll describe what happens in more detail. (Feel free to correct my terminology so I can communicate in a more concise manner next time!)
1) Bootloader comes up fine and I'm able to select my kernel. (This problem affects all kernels)
2) Then as usual a whole bunch of text goes flying across the screen identifying hardware.
3) During this hardware identification, at the point where all my disks are being identified sd 1, sd 2, sd 6... I get the error shortly/immediately after this.
I cant tell for certain if its immediate because so many mount messages are spewed and I am not sure how to 1) pause the screen or 2) scroll the screen or 3) output this information to a file. But it does sit long enough on the disk identification which is right before the mount errors. I was able to look at a previous dmesg and noticed that dracut comes right after the disk identification, so I think the mount errors are being generated in dracut. (Now whether dracut is the problem or not is another issue) I am able to boot using a rescue usb and mount my LVM manually and then browse the root filesystem, so at least my data seems to be safe!

I believe server section is the best when speaking of RAID stuff...
I have the following situation:We have a DELL T3400 with embedded fake raid on it. I dont know exactly how the system was setup (I wasnt here at that time), but the RAID was enabled in bios and while booting, the two harddrives would be seen as members of intel raid volume0 (RAID 1 mirror). I am not sure if the software raid was actually properly configured in Linux (Fedora 9) and if the OS was reconstructing the whole raid or it was just the bios part that was mirroring the /boot or just some parts of it. Frankly I find these hydrid raids very confusing.Some bad disk manipulation from my part caused the server to crash, but I was able to recover and boot just with one hard drive after using fsck.
I decided to get rid of the raid as it's not the right solution for the application we need it for and decided to go for a traditional single harddrive system and to use Ghost for Linux to clone to a spare disk when backups are needed.So I installed the latest Fedora 12 distribution onto another harddrive and disabled RAID in bios (changed from RAID ON to autodetect, which is the only other option).
Here is what I have now:
/dev/sda has the newly installed fedora 12
/dev/sdb is an empty harddrive that I would use as an intermediate
/dev/sdc is the old harddrive member of intel raid volume0
sdb was partitioned into sdb1 sdb2 and sdb3 and I created an ext3 filesystem on sdb2. The hard drive belonging to RAID volume0 (sdc) has a lot of work done on it and I would like to be able to recuperate the files to the new disk (sda). I cannot mount that old harddrive while in fedora 12, as it sees some unknown raid member filesystem on it probably assigned by the intel raid chip.
So I decided to do it from the other side: to boot from raid volume 0, and from there mount a third intermediate harddrive (sdb) onto which I would copy the documents and then mount the same harddrive from the newly installed fedora 12 and copy those documents from that intermediate harddrive.I can mount /dev/sdb2 from fedora 12 fine and copy stuff to and from it, but not when I boot from the RAID volume 0 harddrive (sdc) with fedora 9 on it. It keeps saying that the partition in question (/dev/sdb2) is an invalid block device.I am stuck here, as my knowledge in this sort of things is very limited.If somebody can indicate me how to recuperate files from that old raid harddrive onto the new fedora 12 drive, I would appreciate a lot.
I plugged in my USb drive into my computer yesterday and tried to delete a folder. I was unable to do so and got the following message
Cannot move file to trash, do you want to delete immediately? The file "my file" cannot be moved to the trash. Show Details Unable to create trashing info file: Read-only file system
So when I click on delete I get another error message:
Error while deleting.
There was an error deleting Case Study Database. Show Details Error removing file: Read-only file system
At this point I can only click on Skip, Skip All, or Cancel.
I have not changed anything on the stick recently so I dont know what is causing the problem.
I am trying to install linux kernel manually, for this I had compiled linux-2.6.36 with minimum drivers and features. Note that ext2, ext3, jffs file system support and sd ata_piix drivers are set as inbuilt kernel modules.
I had two hard disk for my Intel x86 box sda and sdb. I have running linux on sdb from which I can access sda. sda has one partition sda1 as ext3 fs.
I had created following directories at sda1 root, bin, boot, etc, sbin
After compiling kernel, I had copied bzImage, system map files to boot folder. then using 'grub-install' I had installed grub on sda. after installation I edited grub.conf to setup kernel image.
grub.conf
Code:
After this I booted sda by changing HDD boot priorities,And wow I got grub prompt -- linux kernel booted but as soon as it tries to mount file system it dies with error,
Code:
I accept that I dont have binaries for init and no initialization stuff in /etc, but I think problem is I am not able to give correct rootfs to kernel.
I have an ongoing issue that I've not been able to troubleshoot. Upon bootup I get the following text and error, and it stops. ACPI: Aborted because bad gzip magic numbers MP-BIOS bug: 8254 timer not connected to IO-APIC Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block (0,0)
