The problem is that in Gparted view, the order is not like sda5, sda6, sda7, ...but the order is like:

I got ubuntu 10.04 lucid lynx along with windows (dual boot) and using Grub. On my computer, I have my C:/ (programs) and D:/ (data). I've never used my D:/ before that day that I've lost my windows partition on my grub menu. I usually use my D:/ with windows. The first time I used my D:/ to store data with linux, I lost my windows option in my grub menu. I'm not sure what I did wrong but I do want to restore my windows option in my grub menu.
After "fdisk -l",
I checked in /boot/grub and there is no menu.lst to modify. how I can get back my windows option in my grub menu ?
I had my HD partitioned with Win7 and 2 versions of Xubuntu (32 and 64 bit). and Grub as multiboot loader. I removed the 32 bit version and assigned the free space to the 64 bit version using the Gparted bootCD, but now Grub can't find any partition anymore at boottime. All I get is this message and prompt when I try to boot my computer: error: no such partition grub rescue. My Linux partition is supposed to be sda6. When using the 'ls' command I get quite few entries, from which one is (hd0,6), which is sda6 I suppose.I can list the contents of directories on (hd0,6).I've tried instrucions from this page, but many commands don't work, like 'linux', 'initrd' and 'boot'.I really don't want to loose my current OS's. Is there a way to recover fom this so I get the Grub boot menu with my Win7 and Xubuntu entries again?

So i installed Ubuntu in an attempt to fix it all hoping to get the GRUB. It then booted directly into Ubuntu.So I ran bootsect.exe tx the mbr and it said success.Still boots into Ubuntu directly without and grub.
I ran sudo update-grub

I recently installed Ubuntu 11.04 on a clean hard drive. Everything went well and I ended up giving /home it's own partition. After a while I figured I would dual boot with windows 7 and my mbr got overwritten. Now after this happened I googles how to fix it and found the same answer almost everywhere. It had me go into terminal and run grub an find my partition and setup grub again. All of this was done off a livecd. The only problem was that my livecd didn't have the grub shell installed. Everytime I ran "sudo grub" it would say "sudo: grub: command not found" I tried to install it but it kept giving me errors and I only once actually got into grub, but it could not find my partition. Whenever I typed "find /boot/grub/stage1" it said directory does not exist. So I attempted to fix it my own way. I installed another version of ubuntu along Sid the first. This allowed me to triple boot between the two versions of ubuntu and windows 7. So I booted into my original ubuntu (11.04) and deleted the older version of ubuntu with gparted. I deleted the partition and restarted, but when I restarted I got an error saying that grub could not find the partition. I can boot into my original ubuntu through the ultimate boot cd but it is a round a bout way of doing it. Is there anyway I can set grub to search for ubuntu 11.04 on startup instead of the deleted version of ubuntu?

I have a 9.10 ubuntu desktop on a tower (bought 2004) working fine, and wanted to add a 10.4 server on an additional partition. After install, I stated grub may be newly written, as the list of os was fine. After reboot I got "grub rescue>" I managed to get the system working again, and now I have a grub2 menu list stating correct entries. But when I select the server entry the boot fails telling "disk not found" (The UUID of the partition given is correct, and also shown when accessing the partition from the 9.10 desktop (this needs an additional authentification when mounting) grub shell command ls does not show the partition, all other tools (life-CD, working installation, gparted etc.) do show it normally, I cannot find any difference. The partition is on the beginning of the disk

I can track that my CentOS 5 ships with SVGA driver through:
cat /var/log/Xorg.0.log | grep SVGA
But how can I find the SVGA Version number?
Can someone explain how to determine the number of blocks to determine the number of cylinders for a new partition on hard drive.
Why is block size divided by 1024?
I think I understand unit size is the total bytes per cylinder, I get that. I understand the anatomy of the hard drive (i.e. heads, sectors, cylinders.
My problem is, if I need to calculate the number of cylinders needed for let's say a 20G partition on a 120G drive.
I'd just like to know the max number of logical partitions an extended partition can hold. Is that number different for IDE and SCSI hard drives?

View 5 Replies View RelatedI've compiled and added a kernel in Gentoo before. It doesn't seem to go quite as smoothly in Kubuntu 9.10 These are the steps I followed: I unpacked the kernel in /usr/src and ran make && make modules_install succesfully. Then I copied the kernel in arch/x86/boot/bzImage to /boot/bzImage-2.6.32 This entry is the one given by Kubuntu:
Code:

I just read the script that update grub uses. Changed the name of the kernel from xyz to vmlinuz-2.6.32-generic and it worked.
Everyone who deals with Linux knows that partitions on hard drives are designated as "sdx#", i.e., sda1 sdb2, etc. I know through experimentation that the number portion of the designation is assigned not according to order on the disk, but chronologically in the order they are created.
Further, if you have several partitions on the disk-say, sda1 through sda3-and you delete sda2, the designation of sda1 will remain the same, but sda3 will become the new sda2. The creation of any further partitions on the drive will start with designation sda3 and increment from that point.
At times this creates a conundrum, especially concerning bootable partitions. Some time back I rendered a partition containing OpenSUSE unbootable because of this, even though Ubuntu owned the GRUB bootloader in the MBR. Ubuntu's GRUB could find and point to the partition using the command "sudo update-grub", but when OpenSUSE took over the boot-up process, its GRUB was pointed to the wrong partition and would freeze up.
My question is this:
Under Windows, one is able to make a Drive letter persistent. Windows will keep the drive letter for that partition and assign around it. Is there a way to change a drive designation number, or at least make it persistent, under Linux? It would be a handy method to forestall these types of booting problems, among other things.
Presently, when a person has installed Linux side-by-side with Windows and want to delete the Windows partition and expand the Linux partition into the free space, I will tell them to format the partition, then shrink it to next to nothing instead of deleting it. This preserves the partition ID scheme while giving them the space to expand their Linux partition into...especially helpful with a seasoned Linux installation that would be a PITA to reinstall and set back up.
Oh, and I already know about UUID. This article explains it, but if you look down through the comments, you will see reasons that it is problematic for desktop application and usage. I want to make it as simple as possible for new Linux users (and myself! ).

Now wen i boot into the normal ubuntu linux from the local hard disk, this error appears on screen - "No bootable media present, enter bootable disk and press enter."
I can boot into the installed os by first booting from a live cd, and selecting the "boot from local disk" option. But i cannot boot without a live cd.
I also reinstalled grub-pc package, but no change.
