    I tried to boot into Ubuntu. My monitors told me "there's no connection" and went black. I waited about a minute and nothing happened so I rebooted.

    There are two options for Windows 7 in GRUB. I tried one of them out and it worked great! I'm in Windows right now.

    I assume that Wubi problem was what was causing that black screen, so I'm trying to run a chkdsk on the drive that Ubuntu is installed on. Unfortunately, the drives aren't mapped or something because they don't have a path.

    Here's a picture of what I'm seeing (they just don't show up despite being recognized as partitions in Disk Management):
    http://i.imgur.com/oyIME.png

    So I'm not really sure how to run a chkdsk on a drive that I can't reference...

    I'm trying to google it now.

    Edit 1: I tried to run chkdsk on the drive letters despite them not appearing and it didn't work.

    Edit 2: Ugh. This is terrible... I downloaded Ext2Read because I saw a person was able to get windows to recognize ext drives and assign them letters. I ran the program and used it to permanently set drive letters to them, however, Windows still doesn't know how to read Ext4 format and so it detects the drives as RAW format. When I try to chkdsk it I get this message:
    "
    The type of the file system is RAW.
    CHKDSK is not available for RAW drives.
    "

    I have the sector range from the partition, why can't I just run a chkdsk on those sectors? :'(

    Edit 3: So I read that fsck.ext4 is the linux version of chkdsk for ext4 partitions. I ran it and now when I select Ubuntu from GRUB I get to the purple and white Ubuntu loading screen but it just stays there loading. I've waited about four minutes now, I'll wait a few more minutes before I do a manual reboot... Any ideas on what to do after that?

    Edit 4: Got back into the splash screen and tried to get into a tty via cntrl+alt+f1 so I could run sudo dpkg-reconfigure lightdm. Upon pressing cntrl+alt+f1 I went to a black screen with a tiny white underscore that blinked rapidly. Pressing keys did nothing.

    Edit 5: I ran the Recovery Mode after reading this (I have a 7000 series). Upon selecting any option a fsck.ext4 run appears beneath the menu with a blinking white underscore which I can type into. Typing commands does nothing, but upon pressing cntrl+c I'm brought to the following screen:
    "
    Begin: Loading essential drivers ... done.
    Begin: Running /scripts/init-premount ... done.
    Begin: Mounting root file system ... Begin: Running /scripts/local-top ... done.
    Begin: Running /scripts/local-premount ... done.
    Begin: Running /scripts/local-bottom ... done.
    done.
    Begin: Running /scripts/init-bottom ... done.

    Warning: Fake initct1 called, doing nothing.
    The disk drive for / is not ready yet or not present.
    keys: Continue to wait, or Press S to skip mounting or M for manual recovery
    "
    No key press does anything except for esc, which switches to a white and purple loading screen that says the same warning message. Pressing esc again switches back to the white and black command prompt-looking screen.

    Edit 6: I just ran the system information option in the recovery mode and under the property "=== Software RAID state ===" it says:
    No software RAID detected (mdstat)
    Perhaps that's causing this?

    Re: Trouble installing 12.10 64-bit on a RAID 0 configuration P8Z77-V PRO

    chkdsk is for ntfs partitions. Forget about reading linux partitions from windows, it can only get you into problems. I wouldn't try it.

    If you want to run a check of the ubuntu partition, all you need to do from live session is:
    Code:
    sudo fsck /dev/mapper/isw_blahblah_thefuture7
    That will run the fsck on partition #7.

    The black screen or stucking at the purple screen might be a video issue. I didn't understand whether you did run the commands to install fglrx or not? They need to be run from ubuntu recovery mode, not from windows command prompt.
    In the grub boot menu, select the ubuntu recovery mode. In the menu that shows up, select Network to activate networking (internet).
    After that it will return you to the same menu, now select Drop to root shell.

    That will open command prompt as root. Start executing the commands in that link:
    Code:
    apt-get install fglrx
    aticonfig --initial
    reboot
    You don't need the sudo in front since in the root shell you are already as root.

    See if something like that can help. Usually the nvidia cards were the ones giving problems, not ATI but it seems lately there was a change in the drivers included in ubuntu so you have to do some additional steps for ATI cards too.

    You can also try downloading the driver from the AMD website and putting it onto a usb stick. Then you can try installing it in recovery mode. But try the above procedure first.

    PS. About your Edit6, the message about software raid. The message is correct, you don't have software raid. Linux software raid is different from the bios fakeraid, even though fakeraid is also software based in a way. But it's not linux software raid. So, the message saying you don't have one is correct and that's not a problem.
    Darko.

    That's the thing though. I can't activate network in recovery mode because it does the problem I described in Edit 5. I can drop to root shell, though. The commands don't work without internet, though...

    Edit 1: I get stuck on the splash screen but the orbs below "ubuntu" still turn red/white. It's not frozen.

    Edit 2: HEY!!!! I just found something cool!

    So I did a google search to see if there was a way to set up a network connection via the root shell, and there's a command dhclient eth0 which can do it. It didn't work out in the recovery mode root shell, but I figured I'd try it out in that chroot shell we were having trouble with earlier, and it worked! So right now I'm installing GRUB with your installation guide.

    Edit 3: So I followed what you told me to do and there's a problem, a device which isn't supposed to be being used (at least I don't think it is) IS being used and I'm unable to unmount it. I'll post the full terminal so you can see exactly what happened, but the problem is at the end of it. Is it safe to reboot?

    That's cool, but the boot-repair process already reinstalled grub2 and now you can see the boot menu and boot win7. My procedure will do the same thing as boot-repair, you already did that.

    I assume you will still have the problem when loading ubuntu.

    I wonder if it's somehow connected to the fakeraid array, and whether it's not loading the array correctly. So subsequently it doesn't have the system root partition to mount.

    Now that we can get internet in chroots, though, can't we install those packages we wanted to before but couldn't because of the problem in edit 5? Also, is it safe to unmount that drive?

    I'm not sure which packages are you referring to. It failed when you tried reinstalling grub2, but now that is done. There were not other packages that failed installing.

    I wonder if all of this is consequence of using the live cd, although in theory it should work.

    Are you willing to give alternate 12.04 a try? That should work start to finish, without needing to additionally add grub2. Just remember the array name in case it gets confused in the last install step and asks you to confirm the full array device name which is /dev/mapper/isw_...._thefuture.

    If you decide to reinstall with the alternate 12.04 cd you can use manual partitioning and reuse the existing partitions. Simply select them and set the correct mount points. Format the root partition so that it deletes all old files.

    In fact, if installing 12.04 LTS works fine, I wouldn't even try to upgrade it to 12.10. 12.04 is LTS and is supported 5 years, while 12.10 is standard release and is supported only 18 months.

    The packages I'm referring to are the missing files from the ubuntu installation which might've been causing the hang on the splash screen. Maybe we could install the graphics drivers or whatever?

    I can try 12.04, sure. But first I need to know if it's safe to unmount /mnt/dev, even though it's in use by ~30 different files/programs, because I don't want to mess anything up.

    Ah, OK. You mean installing the fglrx driver. Yes, you can try that.

    Unmounting /mnt/dev should be fine, we only mounted it to use the chroot procedure. Once you are done inside the chroot and exit it, unmounting /mnt/dev should be fine.

    I couldn't get an internet connection established in the chroot.

    I installed 12.04.1 alternate amd 64 bit and it's failed on the "Select and install software" step. I didn't choose the option to install a GRUB. Upon rebooting I got to a screen which had this:

    error: unknown filesystem.
    grub rescue>_


    I relaunched the 12.04.1 installer and ran the rescue mode. When it got to the menu that said "Enter rescue mode" and wanted me to choose what would be the "device to use as root file system" I had 3 options:
    -/dev/sdd1
    -Assemble RAID array
    -Do not use a root file system

    I selected assemble raid array and it wanted me to select which "partitions to assemble" which had 2 options:
    -Automatic
    -/dev/sdd1
    with a "continue" button in the bottom right.
    I tried selecting automatic and hit continue but it brought me back to the "choose a root file system" menu. I went back in and tried /dev/sdd1 but the same thing happened. Selecting both at the same time had the same outcome. I then chose /dev/sdd1 to be the root file system and it said "Mount failed An error occurred while mounting the device you entered for your root file system (/dev/sdd1) on /target. Please check the syslog for more information." I then chose the only remaining option...

    The next menu showed three options:
    1. open a shell
    2. load another root file system
    3. quit

    I opened the shell but it's pretty much the same thing as when we had 12.10 installed...

    /dev/sdd1 is your usb stick I believe. You can't use it as root partition.

    If the 12.04 install failed, maybe the ISO is corrupted or the cd/usb.

    I'm running out of ideas, you can rarely find so many problems when installing. If you have a good ISO and a good cd/usb, installing the alternate 12.04 on your fakeraid should go just fine.
    Stopping at the install software step means something is bothering it. It's not the same like not being able to install grub at the end, it doesn't even continue to that step.

    I don't know what to recommend any more.
    Darko.
