Ubuntu :: Grub Not Detecting Partitions Correctly?

Jul 18, 2010

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.

Ubuntu Installation :: Setup Is Not Detecting The Partitions?

Nov 12, 2010

I bought the new harddisk so was doing a fresh install of ubuntu (Already installed win7)

But ubuntu setup is not detecting the partitions correctly it is showing 4 partitions but I have 5 (and +1 which is created by win7 of 100mb for system usage)

Setup is showing total 4 partitions and clubing all the partitions together and showing as 785gb and one partition is not detected at all and the other 3 partitions only one is correct 100mb win7 system usage partition.

I have 4 partitions ntfs and 1 partitions exFat, I had created exFat hoping ubuntu setup will detect it as different partition but that is not shown in partitions selection menu.

Ubuntu :: GRUB Won't Boot Correctly To OS X Anyway

Jul 10, 2010

I have Mac OS X on a second hard drive, and GRUB/BURG detects 32-bit and 64-bit versions of OS X. Problem is, my CPU isn't x86-64, so I don't need the x64 version. Also, I have to use the BIOS to select OS X, because GRUB won't boot correctly to OS X anyway. 30_OS_Prober detects them despite all my efforts. Is there any way that I can block /dev/sdb boot entries?I have FreeBSD on /dev/sda3 and GRUB won't autodetect it. It's under 40_Custom, but still won't appear.

Ubuntu :: Grub Won't Correctly Recognize OS On Second Drive?

Mar 27, 2010

I have 2 internal harddrives.

I installed Vista on sdb1 and later Ubuntu on sda1.

When I boot up, I am given choice of OS's to boot into. That worked fine until I formatted sdb1 and installed Windows 7.

Now when I boot, I am given the exact same options as before, and when I select the the old "Vista" Menu item, it gives me an error that it can not find some long serial number. The number is not my drive serial number. That number is completely different.

I can still boot into Ubuntu with out a problem.

Now, in order for me to boot into windows, I have change the BIOS boot order. That is obviously not ideal.

Debian Configuration :: Can't Correctly Install Grub On RAID Array

Nov 26, 2015

I'm having issues with a RAID array.

Setup is like this:

Debian Jessie, 2 hard disks, each having 2 partitions: /dev/sda1, /dev/sda2, /dev/sdb1, /dev/sdb2. Partitions were paired during installation, so they form /dev/md0 and /dev/md1. /dev/md0 is the root (/) partition, /dev/md1 is for /home.

At the end of the install process, I chose /dev/sda1 to carry Grub. And I think this is where I screwed things up.

After removing one of the hard drives, there was no boot capability. So, I installed Grub on /dev/sdb, too.
Now it displays the boot menu but cannot find the kernel. This is where I got lost in the process.

Do I need to reinstall the OS or is there a way to fix it? I suppose I have to edit Grub.

Ubuntu Installation :: Adding Partitions To The Grub

Apr 21, 2010

I've using win7 and 9.10 for a few months now. Today I decided to install yet another OS, but during installation a new grub was written to the mbr. Result: I can no longer boot Ubuntu.This is what my menu.lst looks like

Quote:

timeout 10
color black/cyan yellow/cyan
gfxmenu (hd0,4)/boot/gfxmenu
default 0

[code]....

I can see and mount my 9.10 partition just fine from the new OS, it's located on dev/sda6.And I'd still very much like to keep using Ubuntu. So, how do I go about editing this file to make it work?

Ubuntu Installation :: Moving GRUB Across Partitions?

Jun 27, 2010

I have two "Ubuntu" installations, for the record. My HDD is laid out like so:

PRIMARY - First Ubuntu
PRIMARY - Second Ubuntu [XBMC Live]
4GB Free
14GB LOGICAL
-4GB Free
-10GB Swap

Now, GRUB is currently on XBMC Live. I have terminal and root access if needed, and a "Live CD" ready to use. What I want to know is how I can move GRUB, preferably on its own partition but it can go back the the first partition.

Ubuntu :: Resizing Partitions With GParted And What Will Happen With Grub

May 7, 2010

I want to resize and eventually remove some partitions on my drive but I need to know how this will affect grub and what to do if I need to fix it.I currently have 3 standard partitions and 1 extended partition on a 160Gb drive.

1st Partition -Windows XP about 60Gb with about 35Gb used. NTFS

2nd Partition -Ubuntu Lucid 10.04 amd64 about 40Gb, 22Gb used ext4

3rd Partition -Linux swap about 2.5Gb

Extented Partition -Ubuntu 9.10 about 49Gb with 23Gb used ext4

I'd like to shrink the Extended partition down and add the space to the 2nd partion where Lucid is. Eventually, I'll want to delete the whole extended partition and add all the space to the Lucid partition.

After using GParted to resize these partitions, what will happen when I boot? Will I need to tell grub where the swap and 9.10 are? I am not changing the start of the first two partitions so I would assume there will not be any problem with them (I'm not sure how moving the start of the swap might affect the Lucid installation though).

Ubuntu :: After Partitions Resize Grub Cannot Boot Win7

Apr 22, 2011

I've resized partitions with some program - perhaps even gparted - but from Win7. partitions are indeed resized, but now I can't boot Win7, grub says:
"No such device found - No such partition found".
I tried to use some advices on similar problems I found here (like adding GRUB_PRELOAD_MODULES="part_msdos" to etc/default/grub and running grub-mkconfig after), but nothing helped. I guess I could restore win7 with installation dvd but I want to fix GRUB (and have both ubuntu 10.10 and win7)

Ubuntu :: Not Booting - Reinstalled The Grub Boot-loader Onto Different Partitions

Computer StatisticsiMac (Model No. A1225) Dual Boots Mac OS X Partition Layout/dev/sda1 = EFI /dev/sda2 = Macintosh HD (HFS Format with Journaling) Free Space (32 GB) I had the linux installation program automatically partition the free space into three partitions. I forget what they were, but I know they are correct.

I tried doing a rescue installation, and reinstalled it many times with different settings. I even tried a manual partition according to instructions from the internet and reinstalling the grub boot-loader onto different partitions. I have reinstalled it at least 5 times!

Fedora :: Grub Not Appearing Even Though Other Partitions Recognized

May 11, 2011

I had tried many distros over the years but settled on Ubuntu for the last two or three, unfortunately the new version of Ubuntu (Natty) has prompted me to make the change again. To keep access to all my Ubuntu docs e.t.c. I installed Fedora 14 on a seperate partition and hey presto, there's the Ubuntu partition for me to read from, problem is that my laptop still just boots straight into Fedora, this is ok on my laptop but I wanted to make the switch on my desktop as well which has the wife's Windows partition on it, not being able to boot into that would cause eruptions! The problem is that Fedora hasn't installed a Grub menu.

On advice I typed this:-
[eric@Eric-Fedora ~]$ grub-install -v
and got:-
grub-install (GNU GRUB 0.97)
[eric@Eric-Fedora ~]$

Mar 29, 2010

i'm trying to install 98se to a 110gb partition so i can dual boot with ubuntu 10 for 98 and 100 for ubuntu after the resize. when i tried making multiple partitions manually for ubutnu putting it on separate partitions i got grub boot errors. the problem i am having every time i try to install 98 it forces me to scandisk it then i have to hit space bar to fix every error i thinks it finds wich is impossible to press it 2 million times. now if I format in a non 98 format and tell it to format in lba it keeps asking for a boot disc, i burned one off but, still kept asking for it. if i do it in non lba, it only saw 2 gigs in 98 and when i went to install ubuntu it was a giant hard drive no partitions. i did try making 3 fat 32s 1 for 98 and then swap and linux partition but, the i got grub errors 17 and 18.

the problem is that bios a cap of 130gb for each drive or in this case partition. it's 320gb WD blue Scorpio. the short i want to dual boot 98se and ubuntu 9.04 with 2 fat32 partitions for storage 110 +100 + 80 = 320 also some visuals.

Fedora :: Merged Two FAT32 Partitions - Grub Broken?

Sep 14, 2009

I have 2 fat32 partitions that I use for things that I share between windows and fedora
I decided to merge them into one partition so I did this with cfdisk by deleting them creating and creating 1 large fat32 partition with the free space. When I boot my machine I am presented with:
grub>
I used the fedora cd to "rescue a broken system" and everything seems fine? I didn't touch any partition besides my extra fat32 partitions and my /boot partition is bootable. How do I tell this minimalistic grub to use my normal grub.conf?

Debian :: Recovering Grub After Windows Installation - Encrypted Partitions And LVM

Nov 4, 2010

I'm running Debian Squeeze AMD64 with full disk encryption and LVM. After reinstalling Windows 7 I lost GRUB from the MBR. I managed to install GRUB after following this guide and using an Ubuntu 10.04 graphical installation disc, but I only get to a GRUB CLI when booting, so I can't actually choose an OS there.

I tried following this guide but I'm stuck after "# Mount the partitions to /mnt/root" and don't know what to do.

Does anyone know how I can fix GRUB so I get to choose between Debian and Windows 7 there?

General :: Upsize Partitions On New HDD - Dual Boot (11.04 On Win7 With Grub)

Aug 12, 2011

I have been an MCSA for the last 20 years, but recently I have been very impressed indeed with Ubuntu 11.04, having dabbled with and then discarded Susi Linux some five years ago. My problem may be summarised as outlined below: Using the downloadable ISO I installed Ubuntu 11.04 as a dual boot on a Win7 100GB HDD on my Lenovo T61 laptop. No problem they both rock and I'm very impressed. During the installation procedure I selected the largest partition sizes available from the Ubuntu installer wizard being 25GB Extended split into 18GB Ext4, and 3.2GB and 3.2 GB swaps (I couldn't suss out any way of manually increasing them any further).

I found that the 11.04 Startup Manager application didn't work at all, so I downloaded and installed Grub Customizer 2.1..and that did work after a fashion.. certainly enough to actually effect changes in the grub configuration settings. Everything worked so well on the 100GB HDD that I decided to transpose the entire disk image to a new 500GB WD Scorpio and make the dual boot my main working disk. Using Acronis I imaged off the 100GB installation selecting the partition by partition, and retain disk signature options. I then recovered the image to the new 500GB HDD and everything works beautifully on the new HDD.

Except of course all the partitions are still the same size. I won't waste your reading time recounting everything that I have done using Acronis Disk Director (V Good) and Gparted (not so good), but needless to say whatever I do Grub won't have it, and I have lost count of the times that I have re-recovered the good image. Basically I want to increase the partion sizes to apportion larger partitions to both Win 7 and 11.04 and obviously I'm missing something somewhere.

Fdisk -l -u produces..
Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors
Units = sectors of 1 * 512 = 512 bytes
