Debian Installation :: Grub2 Doesn't Recognize The UUIds - Invalid Signature
Aug 11, 2010
I have /dev/sda with Squeeze and Win 7 on it, and /dev/sdb with Squeeze. I've managed to get Grub 2 to boot from /dev/sdb1, but only by disabling /dev/sda from being a boot option in the BIOS. When it is available to boot, and lower priority than /dev/sdb, grub does not recognize the UUIds of the disks. So, I've disabled it for now and can boot from /dev/sdb no problems. Trouble is I cannot get Win7 to boot. Grub prints:
error: no such device: f0903a3a903a081c
error: invalid signature
When I boot into Squeeze and run 'blkid' I can see that:
/dev/sda1: LABEL="System Reserved" UUID="F0903A3A903A081C" TYPE="ntfs"
The Grub entry for Win 7 is:
menuentry "Windows 7 (loader) (on /dev/sda1)" {
insmod ntfs
set root='(hd0,1)'
search --no-floppy --fs-uuid --set f0903a3a903a081c
chainloader +1
}
I don't understand how Grub 2 cannot recognize the UUIds. Can Grub 2 to be made to work with volume labels or just plain old /dev/... descriptions? Maybe I should give grub-legacy a go.

I'm trying to install Ubuntu 9.10 on my machine which already has Windows 7 (I want to be able to dual-boot). I had no problems installing Ubuntu but now I cannot boot Windows, I get this error after selecting Windows in the Grub boot menu:
Error: invalid signature
Press any key to continue
When I press a key I'm returned to the Grub menu. There I can boot Linux without problems. I have two 500 GB disks in a RAID 1 array. Windows 7 is installed there. Then I have a 1.5 TB disk where I installed Linux in a partition I created for it. I think the problem may be that I have RAID because this seems to show up as two disks and not one:
more /boot/grub/device.map
(hd0) /dev/sda
(hd1) /dev/sdb
(hd2) /dev/sdc
Three disks and not two.
If I do sudo update-grub I get this:
Generating grub.cfg ...

I have a fairly old computer, (4 years) it is has an Intel Pentium 4 3,4 Ghz processor with 1,5Gb RAM, and had been running XP Home on a 80Gb HDD. About three weeks ago, I purchased a 500Gb HDD, and disconnected my old drive. I partitioned the new drive to 120 Gb and 380Gb. I put XP Pro on the 120Gb partition, and Ubuntu 9.10 on the balance.
On reboot, startup menu (grub?) gave me the option to boot from, among others, Ubuntu 9.10, and XP Pro. Both worked fine! I then reconnected the old drive, and if I wanted to boot up in XP Home, would tap "F8" on start-up, and select the old HDD to boot from. This was working fine and I was happy with the way it worked! This morning, when I re-booted, the Start-up menu now had XP Home added to the list.
If I select either Ubuntu 9.10 or XP Home, they both work fine, but if I select XP Pro, it give me the message "error: invalid signature" and when I press any key, brings me back to the menu.

I took the distribution upgrade from the update manager and can't boot now. Boot into a Live CD (ver. 9.10 - does that matter?), and go through the following steps.
ubuntu@ubuntu:~$ sudo fdisk -l
Warning: invalid flag 0x0000 of partition table 5 will be corrected by w(rite)
Disk /dev/sda: 750.2 GB, 750156374016 bytes

Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x000ad56f
[Code]...
Anyone have an idea here? I have searched a lot and have only found a few references to this issue. Does the invalid flag message relate here? The partition is flagged as 'boot'.

I'm trying to set up an Ubuntu server using 10.04 (64-bit), and running into problems after a couple of reconfigurations. Here's the full story:I initially built the server on a 400+GB RAID5 array, putting everything but swap in one partition. Unfortunately, I needed to repartition, putting / in the first primary partition, swap in the second partition, /var/log in the third primary partition and /home in the remaining space on the fourth primary partition.
However, at this step, I ran into some problems with UUIDs in /etc/fstab and Grub2 (I've used Linux for about 9 years, but I'm new to Ubuntu, and I haven't used UUIDs or Grub2 on Gentoo, yet). Consequently, I made the (probably not smart) decision to move back to the /dev/sdX notation I am familiar with.The problem with that is that now I need even more space on /home, so I've added a Dell Powervault and a Dell PERC5/e SATA card to my server. Now, Grub2 tries to boot from the new RAID array on the Powervault instead of the internal RAID array, so I am trying to move back to the UUID notation so that I don't have worry about /dev/sda being the internal array sometimes and the external array at other times.I don't mind being RTFM'd, but I'm having trouble finding pointers to the documentation explaining Grub2 configuration and the UUID notation. Does anyone have pointers to some readable, concise documentation on configuring this in Ubuntu?

I want to do everything with disk labels. My /etc/fstab is already set up for labels.How can I tell grub2 to use labels? I need it to stop using UUID for root.

I 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 wiped my entire hard drive that had xp as its only OS. I freshly installed a Windows 7 ultimate and everything went perfectly. I then decided to install 10.4. I split the partitions correctly (i had experience doing this already with my laptop, which has xp/10.4). Ubuntu 10.4 install went flawlessly, except for one thing. Now when i boot up the pc, it goes straight into 10.4. I have tried holding shift during the start up to force the boot menu, and it just shows the Ubuntu 10.4 OS as choices. Any clue what i could do to make Win7 appear in the boot menu?

I've bought a HP Photosmart printer, HP Photosmart wireless e-All-in-One printer - B110a and i've got a problem installing it properly. I'm using Debian 6.0 Squeeze. When i connect the printer, Debian doesn't recognize my printer as the Photosmart B109 printer for unknown reason. When i go to the site of HP and search for a driver, it directs me to this site:I've downloaded that latest hplip file as a .run file and installed it. My printer is recognized proparly, but when i try to print a colored image, it comes out black/white. Something is not crrect. Does anyone recognize this problem with this type HP printer?

I've got a box running Etch which seems to have a bad memory controller (I get segmentation faults left, right and centre) so I've built a new 'puter with twice the CPU power (2.4Ghz Intel Q6600 vs Athlon 1000+) and four times the RAM (2Gig vs 512M). I downloaded Lenny three days ago and, apart from some screen resolution issues which I've been discussing in the Newbie forum, most things have been working just fine.
However, I downloaded Opera yesterday (opera_9.64.2480.gcc4.qt3_i386.deb - same version I've been using on the Etch box) and I've seen some strange behaviour. A lot of sites, this one for example, work as expected, but if I go to, for example, www.bbc.co.uk or www.guardian.co.uk, the hyperlinks don't work, the cursor doesn't change to a hand when I hover over the links and clicking over the links doesn't do anything. The same pages work normally using Opera on my Etch box so it seems to be an issue with Lenny, or maybe Gnome on Lenny (I have KDE on the Etch box).

I am having a problem installing Fedora from a CD.When I put the installation CD into the drive and restart the computer, the computer does not recognize the CD and boots automatically into my old version (version 8) of Fedora.I have already made sure that the CD drive comes before the HDD drive in my BIOS settings, and I have already tried using different CDs.

I am trying to make my desktop look like a Mac. I followed the instructions here. Here is exactly what I did:
1. Downloaded the Mac4lin package.
2. Extracted folder in my downloads.
3. Went to System > Preferences > Appearance.
4. Clicked install.
5. Installed Downloads > Mac4Lin_Install_v1.0 > Mac4Lin_Install_v1.0 >b GTK > Mac4Lin_Meta_v1.0.tar.gz.
However, when I do this, it doesn't recognize it, as you can see in the picture. Did I do something wrong when installing it?

Got kernel panic when upgradeing from 9.04 to 9.10... Have a tough time with this sparc server. On newer disto it doesnt regognize the cdrom in installation what will result in no install. I tried all trix I found on internet about this issue but none of them did it for me. So I went back in versions. When I come to 7.10 gutsy everything seems to work, so now everything is up and running.
But now I want it back on version 9.04. Last time (a year ago) I did the same thing, and just do-release-update to current version. Now that doesnt work. Maybe becourse I need some updates to gutsy, and the gutsy repositorys is not available anywere. how I can pass this upgrade to 8.04? I set the APT::Get::AllowUnauthenticated true; to pass this far...

I recently installed ubuntu 10 on my Compaq mini 730ej. I installed it using the wubi software. Although it works fine with regular lAN connection, it doesn't recognize any wireless networks - when I click the icon I see a "missing firmware" massage. Now - I am a linux newbie, so be gentle, but I would very much like to solve this problem since.So what can I do?

I recently installed Ubuntu 9.10 onto my second hard drive, and now I can't boot into Vista (installed on hard drive #1). Grub2 just doesn't seem to be recognizing that there is a Windows Vista installation on the first hard drive.
I followed this guide (with Fabien's changes) because it seemed like they were having the exact same problem. But after rebooting, Vista is still not showing in the GRUB menu. In fact, the GRUB menu doesn't even show up unless I press Shift because it thinks that Ubuntu is the only OS installed on my computer.
My results with boot_info_script:
Code:
============================= Boot Info Summary: ==============================
=> Grub 2 is installed in the MBR of /dev/sda and looks for (UUID=e94a058d-1d19-4a98-924b-1a5fce405bdd)/boot/grub.
=> Windows is installed in the MBR of /dev/sdb sda1:
[Code]....
When I was installing Ubuntu to HD2 (the 500gb one), I got a peculiar message saying that Windows was installed on it. There wasn't anything on HD2 though, because Windows Vista was most definitely installed on HD1.
However, if I chose to overwrite HD1 with Ubuntu, the message wouldn't come up. It seemed like the installer was confused as to which hard drive actually held my Windows Vista install.

I have installed Lucid Lynx more than a dozen times in the past thirty hours and I've almost got it working with RAID. The current problem is with /dev/md0 not existing when grub2 tries to access it. When I boot from the alternate CD in rescue mode, Ubuntu sees /dev/md0 as a software RAID array and I can access the files accordingly. When I boot from the grub2 bootloader, it sits for a while before spitting out "Gave up waiting for root device" and tossing me into the initramfs shell where I can see that /dev/md0 doesn't (yet) exist. What can I change within grub2's configuration to inspire it to start /dev/md0 before trying to mount it?

I have an ATI Radeon 9000 Graphics card that Ubuntu 9.10 doesn't seem to recognize no matter what I do. Knowing that its an older card and that ATI stopped support for it a while ago, I was wondering if anyone knows if I would have better luck on Ubuntu 8.04. I can't get 3d or opengl to work, or install the correct ATI Driver.

First time this has happened. I installed Fedora first (XP already installed) and then installed Ubuntu 9.10 64. Fedora doesn't show up on boot up menu. I've tried update-grub.
Before I would have just edited menu.lst, but now?? I dunno.

I have Ubuntu 9.10, PuppyLinux431 and Windows XP on a Toshiba laptop. I like Ubuntu, but the speed of PuppyLinux is addictive, so that was my default boot until I upgraded Ubuntu which included an upgrade to Grub2.
My problem: Grub2 doesn't recognise PuppyLinux. Using information from [url] I have made an executable file named 07_Puppy in /etc/grub.d and did update-grub from root. Still no luck. I can boot PuppyLinux from the grub command line using the following commands:
Just before grub displays the boot menu, I think I see a very brief message about a syntax error, but it's gone before I can read it.
Here is the contents of my grub.cfg:

I'm attempting to triple boot Windows 7, Mac OS X, and Ubuntu 11.04 on non-Mac hardware. Chameleon is my primary bootloader, which is supposed to chainboot into grub2, but all I get when I choose the Linux boot option is a black screen with blinking cursor. If I try to boot Ubuntu while holding shift, I get the word GRUB, followed by a space and a blinking cursor. grub2 is installed to the Ubuntu partition, and attempts to reinstall it there or to the MBR from a LiveCD result in errors. The MBR and GPT partition tables are synchronized. How do I go about making Ubuntu bootable, without breaking my other two operating systems (or at least leaving them recoverable)?
I built a new desktop computer.The goal was to triple boot the system with Windows 7, Mac OS X Snow Leopard, and Ubuntu 11.04. This endeavor has been significantly more complicated than I originally expected, but with the of a forum-goer at InsanelyMac.com, I've managed to get pretty far with a complex installation process. I've attempted to get Ubuntu running using two methods, neither of them achieving what I'm hoping. Both methods follow.
In the first method, I install Mac OS X using a specially designed install CD that boots into the Snow Leopard installation DVD. The disk is partitioned to have a FAT partition, followed by a Mac OS X journaled partition, ending in a second FAT partition. Mac OS is then installed to the second partition. The Windows boot CD is then used to format the first FAT partition as NTFS, which Windows 7 is then installed to.
As I'm sure you know, this installs Windows Boot Manager. Then I boot into OS X using the boot CD mentioned earlier, and install Chameleon, a bootloader specifically designed for Hackintosh systems, and (supposedly) capable of booting into all three operating systems I'm trying to work with. Finally, I divide and reformat the remaining FAT partition into an ext4 partition and a swap partition, and install Ubuntu to that ext4 partition, with the bootloader installed to the same partition. This will break the Windows bootloader, as now the MBR and GPT tables are no longer syncronized. Ubuntu is also unbootable; attempting to chainload into grub2 leaves me at a black screen with a blinking cursor. The former problem is solved by booting into a LiveCD and installing and running gptsync. Windows is now bootable, but Ubuntu remains in 'limbo'.
The second method I attempted is very similar, but deviates in the last few steps. After installing Windows, I instead install Ubuntu 10.04 LTS, as I thought I might have fewer bootloader issues with that distribution (don't ask why; it was a lucky hunch).This breaks Windows Boot Manager, but this time grub2 throws me into the grub> prompt.I can boot into Ubuntu just fine using the set root/linux/initrd/boot commands, but my motherboard's Ethernet port is not detected by the OS, so I can't directly download and run gptsync. Once I do manage to run it, though, Windows is then also repaired.
Unfortunately, since I can't access the Internet, I can't do a distribution upgrade that way. Trying to upgrade from the recent release's LiveCD...well...doesn't upgrade, just overwrites. So I get the same black screen with blinking cursor problem. I've tried reinstalling grub2 through a LiveCD using grub-install both using the --root-directory flag and the chroot method.

I have been upgrading from 9.04 to 10.04. Now, I want to install 10.10 from the beginning without losing the data in my current partitions but when I run the Maverick installer it recognize my disk as a whole with no partitions. From another posts, I suspect that the problem is in the partition list because it seems to be a duplicate partition but don't know how to fix it. This is the fdisk output:
Code:
jgarcia@jgarcia-laptop:~$ sudo fdisk -lu /dev/sda

I recently have installed Ubuntu 10.10 Maverick Netbook Edition in my personal netbook. The thing is that I had installed Windows 7 in the hard disk drive so I decided to install Ubuntu alongside with it. After the process of installation everything was cool but I hadn't the Grub working. I then pressed the Shift button during the booting process so I got the Grub menu but it didn't show the Windows 7 partition. The Windows installation was not erased because its file system is present in Nautilus. I have tried reinstalling the Grub a thousand times but nothing changes. I have attached the results of the boot info script so you can have some info about my booting configuration.
