As the Title states, "update-grub" does not detect the windows xp partition on /media/sda1. And, when I attempt to mount it from teminal nothing happens, and from nautilus I receive the following error: "Error mounting: mount exited with exit code 2:
mount: only root can mount /dev/sda1 on /media/sda1" I am root.
I've searched quite a bit and cannot find a solution to why using update-grub cannot detect my windows 7 partition Here is a log of the bootinfo script(hopefully it pastes correctly...)

I installed Ubuntu 9.10 yesterday on my computer. I had Windows XP and Windows 7 (I deleted the Windows 7 partition and installed Ubuntu 9.10). However, after installing Ubuntu, I couldn't access the grub boot menu. So I googled, and I found out how to make the menu show up again. That was okay. But Windows XP didn't show up. So I googled a bit more, searched the forums, and I added the following entry to my 40_custom file code...
As far as I know, that should work. The uuid I entered there is the one that gparted told me was the uuid of the partition. However, this isn't working. I get a disk read error when I try to boot my Windows XP.
According to my gparted, my Windows XP drive is inside an extended partition? I wonder if that has any influence on why I'm getting the disk read error, or anything. It's either that, or my 40_custom entry is wrong. I've been trying to sort this out for a while now, and I'm afraid I'm not getting anywhere with it.

I went through so many post but I haven't found the proper answer yet hope you have an Idea1. Grub2 saves only Linux OS as last selected no Windows OS2.It is possible to boot into a cdrom (drive)?

I installed Ubuntu9.10 on a USB hard drive attached to my laptop. Laptop has pre-installed XP in the in-built hard-drive. Point to be noted is that my hard-drive is protected via encryption software called Pointsec.
The installation of Ubuntu on the USB hard drive went through fine and I'm able to boot Ubuntu from it.
But now the problem is, GRUB2 fails to detect the Windows XP installation.
Can someone tell me how I can force GRUB2 to boot Windows XP from hd0,0?
The GRUB1 way of configuring /etc/grub/menu.lst does NOT seem to work with GRUB2.

I'd like to have a dual-boot system with WIN7 and Ubuntu. I already have Windows 7 installed. I tried the 9.10 installation but the partitioner says i don't have any Operating Systems installed. I read a few threads about this type of issue and i didn't find any solution. Then i found a discussion saying that there is a problem with GRUB2 in 9.10 and that the problem is not present in 9.04. Then i tried the installation with 9.04 but got exactly the same problem: the partitioner does not detect Windows 7. Basically i have this system:
- Windows 7 Professional x64
- 1 TB HDD with 4 partitions with 100Gb each (NTFS)
- ~600 GB unpartitioned free space
- Processor Intel Core 2 Quad Q8200
- ASUS P5Q MOBO
- ATI Radeon HD 4550
I tried both the x32 (i386) and x64 (AMD) versions of 9.10 and the x64 version of 9.04. I don't have the WIN7 partition that some installations seem to have, at least i don't see it under Disk Management (Computer Management).
I booted into Windows 7 three times this summer and each time I did, upon restart grub was missing. In fact, the computer couldn't find any operating system, and displayed an error "No Module Name Found".

I upgraded a while back to Windows 7. I run two separate HDDs, with debian on sda and windows on sdb.Everything worked fine, up until i upgraded to windows 7. The installer forced me to unplug sda and make sdb primary. After installing I repositioned the HDDs and was stuck with a "NTLDR is Missing" messageAfter removing the search -fs--uuid tag from grub.cfg, Windows 7 booted for a good 0.5 sec and then rebooted. All that flashed was the "Starting Windows" page. I see similar bugs reported in the launchpad, but nothing that directly parallels this Here's my windows entry in grub.cfg:
Code:

I've installed Xubuntu 10.10 on a very new EeePC 1201HA. The netbook came preconfigured from the OEM with the disk split into two Windows partitions of about the same size, one with Windows 7 starter. I removed the second partition (Which was just empty) and have installed a series of different distros since then, to try and gauge their support for the 1201HA hardware. I finally settled on Xubuntu, which can support most of the laptop's features with some tweaks.
However, after this last install, and a Grub config change needed to make the framebuffer work on this hardware, I'm unable to boot Windows 7.Grub shows it on the menu normally, but when I select the Windows 7 entry, I get the message 'Reboot and select proper Boot device or Insert Boot Media in selected Boot device and press a key,' which I understand isn't from the OS but rather a BIOS message which implies there is no loader.
I've tried using the Windows 7 system restore to do everything short of rewriting the Windows bootloader to the MBR (Which would, of course, remove Grub and thus not solve my problem, as I couldn't load Ubuntu from it). I attempted to fix the boot sector on the partition with the system restore tools, to no avail. And because this is a netbook with no optical drive, I'm unable to reinstall from a disk.
So to make things short, here's my situation: I was having the "no module found" problem, because dell software kept on messing with the MBR So I restored the MBR using Windows recovery and deleted the dell software Re-installed ubuntu 10.10 off the liveCD ~Then I had problems getting GRUB2 boot menu to show at boot, but i fixed that~ Now I'm having the problem where whenever I try to boot into windows 7 through GRUB2 instead of booting windows I just get:
"bootmgr is missing"
Note: I can still boot into Ubunutu 10.10 just fine.
I installed Ubuntu 10.10 on my computer from a USB. I did not use wubi to install ubuntu. The computer already had Windows 7 installed. According to gparted, Windows 7 is installed in sda1, linux swap space is in sda2. Then sda3 is shown as a drop down menu containing sda5, where linux is installed. A picture to show this is attached . sda4 is a recovery partition that came with the computer.
The problem is that Windows 7 sometimes boots, and sometimes it does not boot. Most of the times it does not. Ubuntu boots perfectly. The process to boot is the usual, turning on the computer, wait for grub to load. If I pick Windows, it goes to the splash screen (which is by the way not the usual windows 7 splash screen, it resembles more the vista splash screen, picture attached. I do not know the reason, and I have no idea if it has anything to do with the problem) About 80% of the time, it simply reboots a few seconds after the windows splash screen is shown. The reboot takes me back to the usual HP splash screen, then grub again. The other 20% of the time, it boots normally and works perfectly well.
Right after I installed ubuntu Windows was shown in grub as installed at sdb1. I updated grub and now it is shown as sda1. I already tried some grub custom entries for loading Windows differently, but they all present the same problem. Please do not discard a custom entry as a solution, as the source I used for these custom entries was not entirely trustable.
I also tried popping in the windows installation disk and trying a system repair, but apparently no errors were found.
Reinstalling grub using Ubuntu live cd (booted from a USB) did not work either...
i installed ubuntu / under /dev/sda1, then installed Win7 under /dev/sda2, as primary. Extended partition and its logicals are for data.
After Win7 installation, i can restore the grub2 for ubuntu, with grub-install and update-grub2. It can even probe the NTFS partition under /dev/sda2. But at restart, when i tried to go to Win7 selection, it does nothing, screen goes black, blank, with a single cursor blinking.

My windows 7 is not corrupted. it is also not virus-infected. I know what i am doing, and i know my windows is fine. it has been running fine prior to installing ubuntu. I'm just saying this becuz i noticed that viruses are a common response to similar problems like this.
I have looked through many different forums and ..... tutorials on how to get Samba to work. I am new to Ubuntu (Linux in general). I am able to access my shared folders on my Windows 7 system with my Ubuntu system. I cannot access the shared files on my Ubuntu though on my Windows 7.

I am running Windows XP Pro SP3 and it is currently setup on a system running 2 SCSI drives with an adaptec 2940 UW (non RAID) PCI card both are 18.4 GB. Windows XP is installed on the first one and I am trying to install Ubuntu 11.04 onto the second, but the installation doesn't recognize that windows is installed on the first drive and only gives me that drive as an option to install... Gparted recognizes both, one as an NTFS file system (sdb) and the second as a unpartitioned drive (sdc) and for some reason is placing the usb drive as sda which i'm assuming might cause some issues with grub boot loader later on after the drive is removed. what might be causing this issue and how i would go about fixing it... should i just go to 10.04 and upgrade to 11.04 after?
View 2 Replies View RelatedI'm trying to install Ubuntu 11.04 alongside Windows 7, but when I boot from the CD, Ubuntu refuses to detect the presence of Windows 7. I tried unplugging all my external hard drives to see if that made a difference, but Ubuntu still can't tell that I have Windows 7 on there.
View 4 Replies View RelatedI have 2 hard drives, first drive (hd0) is for data, second drive (hd1) is for the OS's. Windows 7 was installed on (hd1) a few months ago and wiped out GRUB. But today, I decided to go back to Ubuntu. I performed a fresh install of 9.10 x64 to (hd2), GRUB2 works and finds Ubuntu (both the newly installed x64, and the previous x86 versions), but it does not see Windows 7. The only goal I have right now, is to make Windows 7 bootable, once again.
My "sudo fdisk -l" (typing manually, so skipping the Blocks)
Device Boot Id System
/dev/sdb1 83 Linux -- where x64 9.10 is
/dev/sdb2 f W95 Ext'd (LBA)
/dev/sdb5 83 Linux -- where x86 9.04 is
/dev/sdb6 83 Linux -- /home
/dev/sdb7 82 Linux Swap / Solaris
/dev/sdb8 87 HPFS/NTFS -- Windows 7
Things I've tried so far:
1) Automatically finding Windows: sudo update-grub2
2) Reinstalling grub via Live CD (9.10): sudo grub-install --root-directory=/media/(where sdb1 - x64 Ubuntu is) /dev/sdb
3) Forgetting Ubuntu altogether and fixing boot using Windows 7 - bootrec.exe /fixmbr; bootrec.exe /rebuildbcd
Now, number 3 is interesting, I found out that where Windows is installed, /dev/sdb8, is a logical partition, and cannot be made active (bootable). This led me to try number 4:
4) Updating /etc/grub.d with custom 40_Win7 file, and making it bootable (the GRUB makeactive, GRUB2 parttool command):
echo "Adding Win 7 to Bootloader" >&2
cat << EOF
menuentry "Windows 7" {
insmod ntfs
set root=(hd1,8 )
parttool (hd1,8 ) boot+
chainloader +1
} EOF
When I update grub.cfg after trying #4, it gives me the "not a primary partition" error. So now I am confused. Windows 7 was able to boot previously from this very partition, and I don't think installing 9.10 would change a partition type from primary to logical. So, why can't it boot? More importantly, what can I do to boot Windows 7?
I have windows 7 in RAID 0 and installed Ubuntu 9.10 to another Sata drive. Ubuntu is working fine but if I try to boot windows in the Grub2 loader it goes do error and lets my to restart. I have finish the windows system recovery and setup repair several times and it won't find any problems. I can't get to windows loader.

I have a asus eeepc 1101ha. With Karmic,it would boot into w7 without problems.I installed Lucid on another partition,and after that the w7 grub entry would leave me with a blinking cursor in the left top corner, and hang.
I booted with the w7 dvd, ran bootrec.exe to restore mbr and bootmgr, and the booted into w7 to confirm. It was working. Then I booted with the live dvd, mounted the lucid partition, and installed grub. Now choosing the w7 entry would ask for the boot media, and pressing any key would bring me back to the grub menu. Lucid and karmic boot without problems.
Installing grub from karmic now gave the same error. Running update-grub didn't change anything.As I had to use w7, I booted again from the dvd, and restored again mbr and bootmgr. Booted into w7, used it, then once again to the live cd, to reinstall grub, and once again the w7 entry in grub makes grub ask for the boot media.I've attached my boot info script.Ah, I also played with the bootable flag for the /dev/sda1 partition, but it didn't change anything.
I installed Ubuntu in my new notebook. It originally comes with Windows 7 installed on it.Everything works nice however every time i boot into Windows7 the grub menu doesn't work any more. i can't boot into windows or ubuntu any more.
