So first of all, I have absolutely no idea what I'm doing. I'm trying to install Ubuntu 14.04 along side Windows 7 using the windows installer included in the download, but then when I go to restart and finish the installation, I get this error: https://i.stack.imgur.com/vIQTj.jpg

I at first figured this to be a simple download error, retrying the download twice more after that (once in the browser, once in a torrent client), verifying the MD5 sum both times, with neither download working.

As stated earlier, I have absolutely no idea what I'm doing with installing any operating system other than Windows, so I'd really appreciate some guidance as to if I'm doing something incorrectly.

Thanks!

  • It is a hardware failure. It could be the GPU - try booting with nomodeset. If that does not help, check the hardware (clean the dust, re-plug cpu, memory, graphics card, try a different CPU etc.) I found the same "Exception: 5 Bank 4" error reported by a user on freedesktop, who eventually fixed it by replacing his motherboard. Does Windows 7 work ok? Interesting that the Linux kernel of the installer booted without error. – bain May 22 '14 at 00:35
  • What PC is this? Laptop? It seems there is a bug in a common wifi driver which could cause a machine check exception at boot. – bain May 22 '14 at 00:39
  • It's a laptop. Windows 7 works without problem, and how would I go about booting with that condition? I honestly am entirely new to this. Thanks. – BoredomKils May 22 '14 at 03:17
  • See How do I add a kernel boot parameter? – bain May 22 '14 at 09:38
  • Since Windows 7 works without problem it seems this could be a software error. I noticed that your log says the kernel is tainted (has closed source drivers loaded). When you did the install, did it say that it detected any hardware that required (or recommended) close drivers? One thing you could try is to do a full install without internet connection (so it does not download any extra packages). – bain May 22 '14 at 09:41
  • I tried installing it without any internet connection, and everything seems to go to plan, it installs just fine with the windows installer, I'll restart to finish the installation, it finishes without issue, until I go to do the final reboot. Once I get there, it tells me it's unable to mount "/tmp" and "/". – BoredomKils May 22 '14 at 19:08
  • Was that for a reinstall of 14.04 (that you got the error mounting / and /tmp)? – bain May 22 '14 at 21:36
  • Yep, and this is filler text. – BoredomKils May 22 '14 at 21:41
  • What Windows installer did you use? – bain May 22 '14 at 21:45
  • The one included inside "ubuntu-14.04-desktop-amd64.iso". – BoredomKils May 22 '14 at 22:11
  • What is the error? Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) ? – bain May 22 '14 at 22:21
  • The only error supplied is:

    "Serious errors were found while checking the disk drive for /.

    Press I to ignore, S to skip mounting, or M for manual recovery."

    Then it's the same for /tmp if I attempt to skip it.

  • Can you run a hard drive checker, something that scans the whole disk for bad sectors? CPU errors, hard drive errors, it does sound like there might be a hardware issue here... is your Windows install also 64-bit? If not, could you try installing from ubuntu-14.04-desktop-i386.iso? – bain May 23 '14 at 10:52
  • Is there one that you could safely recommend? – BoredomKils May 23 '14 at 19:33
  • The one from the hard drive manufacturer is usually best, see the answer to Check Bad Sectors on hard disk in windows 7 for links. – bain May 24 '14 at 19:22
  • Strange, it says my drive is fine. I tested with both SeaTools and Macrorit Drive Scanner which I found recommended by another forum. Both came up clean. Something else, I tried going back a few versions of Ubuntu, and 12.04 will work just fine. Anything after will have issues installing. – BoredomKils May 25 '14 at 14:32
  • It could be a bug in the kernel. What kernel are you using in 12.04? If you take your working 12.04 and install a later kernel, does it stop working? – bain May 25 '14 at 14:52
  • I honestly have no idea how I'd install a new kernel, I just used what's included in the ISO file downloaded from here. How do I find out the kernel I'm using? – BoredomKils May 25 '14 at 16:51
  • uname -a # The problem is that the issues you are describing are rare and hard to debug. 12.04 works. Windows works. 14.04 works until it is rebooted, then mysterious problems happen... Two things you could try: 1. on boot add parameter modprobe.blacklist=b43 2. Select "Free software only" option when you install. Or you could just use 12.04. – bain May 25 '14 at 17:55
  • Sorry it's been a bit, been pretty busy the last few days. Neither of those options worked, but I'll just use 12.04 for now. Thanks for all the assistance. – BoredomKils May 29 '14 at 18:21
