I had a bad experience with 9.04 - I installed some recommended system updates, and the updated GRUB killed my installation (which is WUBI), not letting me boot.
I've now installed 10.04, and some updates have come through, one of which is GRUB. So I'm now looking at the "Configuring grub-pc" dialogue box that's popped up, and there's an option to "Continue without installing GRUB?".
What are the risks here? Is my 10.04 WUBI system going to die if I upgrade GRUB again? Or is it going to die if I don't upgrade GRUB?

After updating the kernel in Wubi installs, GRUB gets messed up. This has caused me to hold off on the HUGE list of updates in my update manager (I have never updated since I first installed 10.04, and this was just over a week ago). Are these updates important enough to potentially risk something bad happening? What is the risk of updating? Is this an issue with all Wubi installs?

I wanted to install ubuntu via wubi, but i had to format my partitions (can't do it on wubi ) so i used a crappy program(i don't remember the name) to get rid of Backtrack4 , because i wanted windows kept for my mom.So, that was the sorry, i've ended up with a GRUB error 22, and a Backtrack4 CD stuck in my DVD-rom.So my question is: Can somewone tell me how to fix error 22? (i've seen some methods online, but i obviously can't put a Windows CD in my DVD rom because the Backtrack4 DVD is stuck in there.

After upgrading Maverick (perfect!) to Natty, I was unable to boot into anything. (kernel 2.6.38). However, through much PITA, I was able to boot into an older kernel. (2.6.35). I completely removed 2.6.38, rebooted, reinstalled it and ran update-grub. However, 2.6.38 is no longer available no matter how many times I run update-grub, and the only option left is 2.6.35. In my humble opinion, the Natty upgrade experience is rubbish. (blank screen, total PC hangs, boots into a blank screen with only a blinking cursor, NVIDIA official driver not working, bootable only into older kernels etc.)

I did the kernel update via Update Manager today. Unfortunately , after this , disaster happened whereby sh.grub> prompt appeared on screen.
I got no idea how to rescue or repair the grub. I installed Ubuntu 9.10 in my E: under Windows 7 partition and labeled as "ubuntu". It has dual boot capability.

I used the update manager to update the kernel and whatever the other recommended updates were yesterday. I shut the computer down overnight and now when i try to boot into Ubuntu 9.10 i get a basic grub shell and when i try commands like "boot" it tells me there is no kernel loaded. I installed Ubuntu with Wubi so it is a dual boot system.
I've tried to access the Linux volume with a live OpenSuse 11 CD but there is no device to mount. It sees the entire hard-drive as if it hasn't been partitioned. I don't necessarily need to fix the installation. I just need to get my files back.

I have a new acer machine which runs fine on 10.10 mythbuntu desktop livecd. Install seemed fine.
Then I ran an update and on reboot I get a kernel panic error. Research on this reveals it as a very deep subject which can consume many hours, so I opted to reinstall.
This time with ubuntu 10.10. I've tried different CDs, liveusb. Same errors.
So, the question is this - where do I concentrate my efforts - somewhere ubuntu doesn't like this machine, or grub. Does a reinstall overwrite the grub install too? Or do I have a bogus grub install I need to purge before I will get anywhere.

I have manually added an entry for Ubuntu in my grub menu, using Yast. But every time the kernel is updated, this entry disappears. On the other hand, the one for Windows, that was added during OpenSuse's installation, is still there. So how can I keep this entry for Ubuntu ?
Edit : when I save the menu configuration in Yast, I get the following message :
Code:
Connecting to deprecated signal QDBusConnectionInterface::serviceOwnerChanged(QString,QString,QString)

Dell Inspiron E1405 - 160 GB drive with 2 partitions - I think only 1 partition was used for windows and ubuntu Used wubi to install 10.04 - both XPP and 10.04 worked fine after repairing the XP install My boyfriend used Referencer (.reflib) in Ubuntu 10.04 to organize and tag about 900 documents. He spent around 9 hours on the project and its VERY IMPORTANT. I am a dumb ***, forgot the project was on the computer and updated to 10.10 via update manager without it backing up. Now I cant boot to XPP or Ubuntu - "error: no such device:", "grub rescue" My main concern is getting the data back. I would rather uninstall WUBI and install Ubuntu on the 2nd partition (wish I would have done this in the first place but 10.04 was my first Ubuntu install and I didn't know any better). I have to get this data back! I have tried the following and cant locate the referencer (.reflib) file or the .docs and .jpgs booted to USB using my 10.10 netbook remix USB install USB stick - I can see the windows files pulled the HD out and connected it to my Ubuntu netbook, an XPH and W7 computers -cant locate data

Ran the updater, went to boot to Win7 to use Photoshop and realized that the grub menu was gone. Ubuntu boots by default now. I tried running "sudo update-grub" at a virtual terminal and while it listed the various linux kernels ok, it then got caught in a loop spitting out some crazy looking errors. I rebooted and Ubuntu came up fine. I tried running "sudo update-grub" again from the gnome terminal and it hangs the whole computer for a few minutes and finally gives me this:

So, I converted a Vista user by enticing her with WUBI. She's a computer idiot, and she thinks Linux is great.
HOWEVER, she recently had Ubuntu muck up for her, so she uninstalled WUBI/Ubuntu and reinstalled it (9.10). Upon restart, GRUB presented no boot menu and went straight into Ubuntu. The funny thing is, under the GRUB configuration files, the timeout for the boot menu is set to 10. I tried the following (made sure to change the boot device to hda1,0 since fdisk shows her NTFS as /dev/sdb1):
[URL]
No luck. No boot menu, no Windows option. I also tried the following:
Manual Windows Entry (with /etc/grub.d/30_os-prober made unexecutable)
Code:
#! /bin/sh -e
echo "Adding Windows 43_custom" >&2
menuentry "Windows Vista 43_custom" {
insmod ntfs
[Code]....
Using THIS method, the boot loader did appear, but there was no Windows option. Odd. So, I'm at a blocking point. Yes, I was smart enough to run update-grub Thoughts? My replies may be a bit delayed - she's 2 hours away and I don't have direct access to her computer.

I have been using Wubi for a few weeks now and I am really impressed. I have endured a lot of problems with grub and kernel problems etc but now realise that its just the Wubi inside windows! I have it all set up with the cube to perfection and all drivers are running great after a bit of tweaking. So a bit of a lazy question really, can I install it properly onto my drive, and retain all the hard work I have put in setting it up? I have tried, but when it comes to selecting the drive that the Wubi is installed on it just says format with no backup option.

I installed 9.10 with wubi and lately I had a boot problem with the result is that it boots to a grub prompt. I tried several commands, but no success. I thought I hosed the system. [URL]. Once I copied the new wublidr file over, that did it! Give it a shot, as it works.

I've been running Ubuntu 10.04 AMD64 on our home theater PC through a wubi installation. Yesterday the system update installed a new kernel and today there is a problem booting the computer so I'm reluctantly using Windoze to type this. there isn't much information: the computer has always booted fine before the kernel update. When I select Ubuntu in the boot menu the screen goes black and the computer restarts. No error messages, no GRUB menu, just a blank screen before restart.

I beleive I had version 9.x installed. I upgraded once and everything was fine. I went the upgrade manager again and it found some more upgrades. The upgrade messed with grub. It then told me there were no new upgrades. Then I rebooted and it says
Try (hd0,0): NTFS5
Then the screen clears and there is some text I can't read and then it says command not found. Then it reboots.
Is there a way to fix this?
If not is there a way to recover the files from the disk image file.

So after a win7 wubi install, I updated through system update. Now after I choose ubuntu in the win bootloader it takes me to a grub screen. How can I boot into linux and remove grub? (This isn't my computer otherwise I would dual boot and let grub take care of it).

My Wubi installation of Ubuntu (version 9.10, I think) that I recently installed was working fine at one point, but now it isn['t. I select Ubuntu instead of Windows from the Windows boot loader, but instead of getting the usual menu of different linux versions (I think 2, as I updated it at same point), and Windows, I get the GRUB command prompt instead.I've looked at th2e Wubi Guide (https://wiki.ubuntu.com/WubiGuide), and I've followed the instructions for "How can I access my Wubi install and repair my install if it won't boot?", but that reveals no problems.For the record, I'm fairly new to linux and ubuntu, but I'm good with computers generally. The main operating system on my computer is Windows Vista, but I'm currently typing this from a Live CD of Ubuntu 9.10. The virtual disk (root.disk), is currently mounted as vdisk, as indicated in the Wubi Guide.
Ideally I would like to get Ubuntu to load as it used to (with a menu). However, if there is a way to boot from the GRUB command line that would be good too. I'm not at all familiar with GRUB, and the commands I've tried (boot and linux, I think), get errors saying no kernel specified, or loaded, or something like that.

I had Windoze 7 on my wife's laptop, it started running crappy so I install Ubuntu 9.10 via Wubi (so it is not a partitioned dual-boot). I did the latest update, which I think included a kernel update. When I rebooted and chose Ubuntu from the windows dual boot window, instead of loading the GRUB I see an error message flash:
Code:
TRY hd0: NTFS no Wubi(something-or-other)
it flashed almost too fast for me to catch - it took about 10 reboots to figure out that much... and then it goes to a screen that says
Code:
GNU GRUB version 1.97~beta4
sh:grub
I tried several different commands (you can prompt it to give you available commands by hitting TAB), but it said it couldn't detect a kernel. Also, before I updated, I had tried to install iTunes via these instructions. iTunes seemed to have installed fine, but I hadn't tried it yet.

On my laptop running Ubuntu 10.04 I have edited /boot/grub/grub.cfg in order for the shortcut keys for changing brightness and volume to work. I added
Code:
acpi_osi=Linux
at the end of every kernel image line, and it works ok. The only problem is that every kernel update overrides the grub.cfg and therefore I have to reedit the file over and over again. So the question is, where could I put the mentioned kernel startup parameter, so that it doesn't get lost on every kernel update.

I'm running a dual boot Vista/Ubuntu Jaunty. I made some changes to the grab menu so that my windows OS would appear at the top of the list .I know I could have changed the default so that Vista would have been highlighted instead of Jaunty. But the reason I moved it to the top is because when I do a kernel update, I would still want Vista to be the default booting OS. Anyways, after the update my Vista OS disappeared from grub. It didn't get deleted because the Vista partition is still accessible from Jaunty. Can anyone help me boot into Vista and preferably make it the default OS even after a Kernel update? I attached part of my menu.lst .

I run Ubuntu and yesterday the update manager downloaded a new kernel I think. It asked me to restart. I unlike before where when I select Ubuntu at boot up time and it just goes into it I am getting this black screen called GNU GRUB. What do I do here? Has Linux got corrupted by the updates I downloaded?

I have some pending upgrades, one of which includes kernel 2.6.32-22 but whenever the upgrade gets to running the update-grub command, it gets stuck on "Found memtest86+..." Here's the actual output...
[Code].....
It's been hanging like this for hours today, preventing me from getting any of the pending upgrades. I've cancelled it several times, deleted the dpkg lock files and tried it again only to have it hang all over again.

Over the past few days I have been trying to install an older kernel (kernel 2.6.28.1) on ubuntu 9.10 64-bit WUBI installation. I compiled, installed, and updated my grub for the kernel. When I reboot, the grub menu correctly gives me the option of booting into the older kernel but when I do so I receive the following error message:
error: you need to load the linux kernel first.
I am at a complete loss on how to fix this. I even downgraded grub but I still get the same error.
