I have Ubuntu 9.10 and Win7 both installed on my desktop. I use Windows for gaming (when I actually have the chance...) Anyway, for some reason update-grub is not detecting my Win7 installation, neither is os-prober. I attempted to add a custom Grub2 entry to point to Windows 7, however, when I select it from Grub, I simply get a black screen with a blinking cursor in the upper-left, after waiting 20 minutes, Windows still hadn't loaded.
Here are hopefully all the relevant files:
sudo fdisk -l

I installed normally Ubuntu in my lenovo laptop, but GRUB shows two installations instead of one. Whatever happens to one of them, happens to the other, except some command-line work.

My set up is internal hard drive Windows 7, external Ubuntu Karmic. The reason I have it this way, despite Linux being my main OS, is because my internal hard drive is 6 years old and half the capacity of my external new one. Have tried quite a few set ups with various Linux platforms, but have finally settled on above. As yet, I don't know Linux or Ubuntu all that well. Getting somewhere, but it's a steep learning curve.
Because of constant errors reinstalling WinXP - umpteen installations and it keeps crashing - the problems are with security updates and SP3 - I finally bit the bullet and intalled Win 7. I only need Windows for a few essential programs or I'd happily never look at it again, so it filled me with horror doing this, but I couldn't take the crashes any more. So, today, Win 7 installs just nicely. However, I can no longer boot my external Ubuntu hard drive. The error is, 'Grub loading stage 1.5... Grub loading please wait... Error 15'. I load up the live cd, but when I try to follow instructions given to other people with Error 15 (editing files, accessing root) I don't have permissions.
I switched over to Ubuntu a while ago and kept my windows installation for games. I have noticed a slight drop in FPS on all of my games ever since, could this be because of installing Ubuntu?

I just started using Ubuntu 10.04 for development reasons and installed Ubuntu on a seperate harddrive with dualboot option with Windows 7.Today Win 7 got an update and I mysteriously got bumped back to the grub screen after selecting Windows boot option, but my Ubuntu was ok. After that I probably did the worst I could, and googled the problem and tried out some years-old advices which messed up my ubuntu boot as well.I am currently using my computer through Ubuntu Live Usb.
View 6 Replies View RelatedI'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 .
View 9 Replies View RelatedI have been phenomenally unlucky with Ubuntu as seen my my post history and decided to dual boot.
I set it all up with a clean install, when I tried to load Windows from Grub the computer restarted. After much headache I managed to set it up correctly (when it wouldn't load from Grub I booted from the Windows CD and clicked on "Repair computer" and it finally worked).
Now I am having the same problem as before--I think my installed all the updates from Update Manager and it included a grub one. Now I can't load Windows from the grub menu: It goes to the Starting Windows screen and then reboots my computer. If I do it again it gives me an error message and an option to perform "Startup repair". When I try to do Startup Repair, the computer reboots after a few loading screens.
So I tried what worked before and put in my Windows 7 CD, and clicked on Repair Computer. BUT NOW it gives me an error message somewhere along the lines of system restore is not compatible with my installation of Windows, and to insert a compatible recovery CD. This is the ONLY Windows CD I have (legitimate copy).
Over the course of this migration experiment I have installed and reinstalled both operating systems 7-10 times total. I'd rather not do it again. My poor laptop is probably wondering what the heck.
I can't stick with Ubuntu alone because my wireless doesn't work with it, my grad school files are not completely compatible with open source software, and I can't play the games I'd like to. So I must have the option to at least dual boot into Windows.
When selecting Windows it restarts the computer entirely to the Compaq screen, not just to the Grub menu, if that matters.
I have a vista/ubuntu 9.10 duel boot laptop. Last week the screen was broken so it went back to the manufacture. Before that I rename the /etc/grub.d/10_linux file and ran grub-update so that Grub will only show windows boot menu (in case it confuses the repairman) now I have the laptop back and I am eating my own medicine.how to restore my ubuntu boot menus? I can now only boot into windows, although it seems like I can go to my ubuntu partition and change back my grub.cfg (which I did not backup!)but I can't remember the menuentry details.Is there any way, other than manually change my grub.cfg, so that I can boot into ubuntu again?
View 5 Replies View RelatedAfter doing my weekly update, I discovered that I am not able to access Windows.
My windows entry still shows in my grub list on the boot menu The windows partition is still there
However, when I select windows as the os from the boot menu, i get a black screen with a white cursor in the top left corner.
Ubuntu's update manager recently updated the Grub menu.lst file. It let me decide if I wanted to keep my old menu.lst or the new one. After deciding that I was fine with the new one, I found out that I can no longer boot into Windows 7. I had previously edited menu.lst so that Windows would be at the top of the list, however, I didn't notice that this had put it into the automagic update area, and I realize now that I should have just edited what the default number was instead of moving around the entries.
Anyways, I can no longer access my Windows 7 OS via Grub, and I was wondering what sort of fix I can have for this. I've tried running update-grub, but it hasn't fixed the problem. The Windows bootloader is on the first partition of the only hard drive, as far as I can remember.
With a bit of help from this forum I managed to install 10.04. The solution was to add i915.modeset=1 to the options when booting up from CD.Now I need to do the same in order to boot up from HD. I've opened /etc/default/grub and changed the relevant line to include the above option. But I need to run "update-grub" and it comes back with an error to the effect that it 'can't find a device for / (is /dev mounted?)Also, the boot menu only has ubuntu - no sign of windows in my intended dual-boot. What can I do?
View 9 Replies View RelatedI am running Ubuntu 10.10. Normally when I boot, I get the choice to run Ubuntu or the Windows loader, where I choose between 7 or XP. I have just noticed that when I boot now, I do not have the choice of going into windows. This has happened on two of my PC's just in the last few days. I assume one of the updates has overwritten the grub configuration file as I still get the grub menu but not the windows option. I have tried sudo update-grub but this did not solve the problem.

I installed Ubuntu first, then Windows 7.
I've been running ubuntu 9.10 until this week without any problems. I've just done an in-place update to 10.04 and now cannot boot my windows XP partition.
looking at grub.cfg it appears to be referring to sdb1 as the XP partition whereas the disk utility says the correct partition is sdb5.
sdb1 is a data partition formatted ntfs but not bootable.
When I choose XP from the grub menu all I get is a black screen with a flashing cursor at the top, which would suggest it is trying to boot the data partition.
I've tried update-grub and also startupmanager and it makes no difference. I would just try to edit grub.cfg but the next update would presumably wipe out my changes.
Looks like Grub2 on my new installation of Ubuntu 9.10 is not picking up a Windows 7 installation on a RAID0 array (using the built-in RAID software from my Asus P5Q-Deluxe)
Here are the results of the boot info script:

View 6 Replies View RelatedI am attempting to Dual boot windows 7 and ubuntu 10.04 on my netbook. When i boot the Live CD from USB, and then go to the installation, then when i get to the partition part, it does not detect windows at all. It says that i have no operating systems installed. Is anyone else having this problem? Sorry if there is already a thread on this, I could not find one with a search.
View 9 Replies View RelatedAfter putting this off forever, I've finally decided to delete my old XP OS and install Ubuntu on it as a dualboot option along with my existing Windows 7 x64 install. However, I'm having a common issue in that both Gparted and fdisk do not detect the partitions of my main boot disk and shows the entire disk as unallocated. I've read a number of similar threads with some great responses from many of the folks here on this forum. I've put together all the info I could think would be relevant.
1) I ran fdisk -l. Here is the output (This is from booting from the live CD). Sorry for the long logfile. I have a number of disks/partitions attached. The relevant disk of interest is /dev/sdb/
Code:
ubuntu@ubuntu:~$ sudo apt-get install gdisk

/dev/sdb contains GPT signatures, indicating that it has a GPT table. However, it does not have a valid fake msdos partition table, as it should. Perhaps it was corrupted -- possibly by a program that does not understand GPT partition tables. Or perhaps you deleted the GPT table, and are now using an msdos paritions table. Invalid argument during seek for read on /dev/sdb
3) And this is a picture of the disk unders Windows 7 Disk Management. "Disk 3" is my main boot drive with Windows 7 on C:. The unallocated partition before it was where the old XP install was. I want to ideally install Ubuntu on that partition. Also, I should mention that "Disk 0" is a Drive from my old DELL PC that has a windows XP installation on it along with the boot info. I left it in there in case I wanted to swap it back into my old PC. However, it seems to confuse Ubuntu during the install as it detects only that XP installation but cannot read/detect the current Windows 7 install.
I have a dual boot setup with Windows 7 and Ubuntu. Lately Windows 7 has been causing me all kinds of grief and I decided that it would be better to just restore it back to factory settings. I have a Windows 7 recovery partition (hidden) that I can see from Ubuntu, however Grub2 does not detect it. It only has two identical Windows entries that take me into Windows (though in /boot/grub/grub.cfg they point to hd0,msdos1 and hd0,msdos2 respectively).
I have searched far and wide on the Internet on how to gain access to this recovery partition to no avail. I even found a link from Lenovo's website that details how to do this in the old version of Grub, though it doesn't work in Grub2.
Here are the most useful links that I have found thus far, both fall short unfortunately. [URL]
I have already backed up all my data, so I can nuke the whole disk if that's what it takes, but I don't actually have a Windows Recovery CD, only the hidden partition which I can't seem to boot into.
I also saw some posts where people were having trouble disabling the recovery partitions from appearing in the Grub menu, their answers often consisted of people telling them that it's not possible to disable the recovery partition from appearing without hiding the main Windows Install, oh the irony!
I have Dell 1530 laptop which comes with windows vista. i just want to run windows xp on that but i am unable to install then what i did is just installed OpenSuse over windows vista(erased) only suse is there now i want to install xp on it but i am getting problems (windows xp CD is not detecting by suse).
View 8 Replies View RelatedMy current situation is I have two physical hard disks, one with Windows 7 (sda) and another where I recently installed Ubuntu 9.1 (sdb). At this time there were no issues.
Now after getting used to 9.1 I selected to upgrade to 10.04 from the update manager. During this install I was told I needed to upgrade GRUB which I understand is the bootloader and was told to choose where to install it.Now at this time I had no knowledge of drive naming conventions in Linux and there was no option to cancel the upgrade to look for help, so instead I followed the advice in the help box to simply select every device listed
The result was a fully working Ubuntu installation but at the cost of an unbootable Windows 7.Windows is showing on the GRUB menu but selecting it gives only a blank screen with a flashing cursor and no ability to do anything besides ctrl-alt-delete.
After a few hours of googling solutions including downgrading GRUB, there was no change and it seems that I actually have a version of GRUB on both drives. The one on the windows drive (sda) is the default loaded GRUB that shows Windows 7 but cannot boot it. The second GRUB install on the Ubuntu drive (sdb) is the one I am able to configure through Ubuntu but does not list Windows 7 on its boot list even after using "sudo update-grub"
I was unaware of the difficulties of installing and booting Ubuntu from the "onboard raid" that the NVIDIA nForce chipsets provide. However, I've managed to get it working reliably with one single caveat:
When update-grub builds the grub.cfg, it refers to all of my partitions as follows:
Code:
menuentry 'Ubuntu, with Linux 2.6.35-27-generic' --class ubuntu --class gnu-linux --class gnu --class os {
recordfail
insmod part_msdos
insmod ext2
set root='(/dev/mapper/nvidia_caifaefg,msdos5)'
[Code]...
So I'm guessing that the whole nvidia_blah,msdos5 is because of that. However, it doesn't seem to explain why Grub would THINK that would work and it in fact does not work. That's the biggest source of confusion on my part.
My questions are as follows: First off, because as an IT person I want to know: Why does this sort of change work? What does changing that device name change in GRUB's behavior? Is there a setting in /etc/default/grub that would change the way it's naming these RAID devices? Is there a value for this setting that would give me the device names that work, as explained above?
If there is no setting change I can make in /etc/default/grub, could I add a sed command on to the end of update-grub or can I make a modification to one of the scripts in /etc/grub.d? What sort of change would be recommended? How would I preserve this change through later package upgrades that would possibly rewrite these files?
I have an old BIOS (only 149 GB detected in 160 GB drive). I have installed very few OS as a result - Windows in first 80 GB , 2 distros (20 GB each) in next 40 MB which is within the 149 GB. On issue of "update-grub" grub seems to detect all OS and generates grub.cfg. But on boot , one distro does not appear in the menu.
