[SOLVED] LiveCD 5.1.1 boot issues
I'm trying to use Knoppix to get into a drive that's supposed to be running Windows Vista Ultimate, but that's acquired some bad sectors and won't run chkdsk. It thinks it's an unformatted drive, which isn't the case because it boots fine into safe mode, so clearly it's formatted and even has an o/s on it. But just to let you know where I'm headed -- supposedly, Knoppix should let me get it back to working condition.
I burned a copy of 5.1.1 at 4x; all the directories and files seem to be accessible, so I think the CD is good. Trying to boot it, I've gotten a series of error messages. Here's one example, booting with options apci=off noapic, which I tried based on posts here that seemed to describe similar problems to what I've had:
"ERROR: CANNOT UNITE READ-ONLY MEDIA AND INITIAL RAMDISK!"
Then three times it prints "Buffer I/O error on device sr0, logical block 354567"
And seven times it prints a two-line error message, "cloop: Read error at pos 720666572 in file /cdrom/KNOPPIX/KNOPPIX, 54341 bytes lost. [next line] cloop: zlib decompression error -3 uncompressing block 15547 131072/0/54341/0 720666572-720720913"
Next it tells me "/linuxrc: /KNOPPIX sbin/halt: I/O error"
And then, curiously, it says ">> Read-only CD system successfully merged with read-write /ramdisk." Wasn't that what it said it couldn't do?
The last bits of the error info read, "/linuxrcl cannot create /var/run/utmp: directory nonexistent [next line] No filesystem could mount root, tried: reiserfs ext3 ext2 msdos vfat iso9660 fuseblk [next line] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(1,3)"
I've also gotten longer strings of errors like the I/O and decompression errors, with it telling me to try passing init= to kernel. I've been trying to boot with init=3, from other posts here, and with that, I don't get the message that it can't unite the media, but I do still get a very long string of error messages; the only new element so far as I can see is "Failed to execute 3. Attempting defaults. . ." and then it comes back to telling me to try passing init= option to kernel. I assume that means init=3 didn't work, but I don't know what might.
I'm reasonably good with computers, but I don't know enough about linux generally or Knoppix specifically to figure this out on my own. Please help!
