View 2 Replies View RelatedI just upgraded by box from Fedora Core 9 to Centos 5.2. Finally!I have a 500GB SATA drive, it's partitioned into three equal size slices, hda1 through 3. The old Fedora was on hda1, I installed the new Centos on hda3. I instructed the installer to write the MBR to /dev/hda, not /dev/hda3. Fdisk says I have sector 0 unused.First, the system wouldn't boot - it just looped through the BIOS, rebooting over and over again. The BIOS sees the disk, but it never loaded Grub. I tried re-running grub-install /dev/hda, and not I get a Grub Error 17 after stage 1.5 loads.
I can boot from rescue OK, the grub.conf man menu.lst look fine, it's pointing to "root (hd0,2)". It's either the BIOS that can't find the MBR, or the MBR can't find Grub.When I looked at the disk with fdisk after the install, hda1 was still marked bootable, hda3 was not, so I swapped bootable flags but that has not made a difference. I also appended the new grub to the old grub thinking I could get the MBR (if it is there) to load the old grub and thence find the new Centos, but that didn't work either.Mobo is an old Shuttle AK35.Any ideas? Did I mess up by not telling the system to put the MBR on /dev/hda3? Is there a way to fix this without reinstalling?
3 partitions (in order): Windows 7, CentOS and shared data partition.
I need to increase the size of the Windows 7 partition (c:windowswinsxs seems to be something not easily remedied).
GParted didn't work in moving things around (bad sector) so I wiped out its partition (# 2 out of 3) and I was able to increase the size of the Windows 7 partition (I can reinstall CentOS easily and not much work lost).
Except ... no more grub menu (unsurprising). This incantation does allow me to boot into Windows 7.
Is there any way of rebuilding the grub menu short of reinstalling CentOS (5.5)?

View 2 Replies View RelatedI have used CentOS for a while and have never run into this issue. I searched all over and didn't see a similar issue anywhere, I did an install of CentOS as a server (no GUI) with only the base. Partition is /boot ext3, size of 100MB. The rest of the drive is partitioned as / with ext3. This is being done on a CompactFlash card of 32GB in size. The BIOS sees it as an IDE drive.
When the install completes and the system reboots, the grub stops at the grub> prompt. There is no menu for OS options. If I do the following commands:
grub>root (hd0,0)
grub>kernel /vmlinuz-2.6.18-194.el5 root=LABEL=/
grub>initrd /initrd-2.6.18-194.el5.img

View 4 Replies View RelatedI am running CentOS 5.5 and I want to create a boot CD so that if my boot partition is moved I can still boot from the boot CD and re-initialize grub again. Is there some easy to use utility which will enable me to do this ?
View 4 Replies View RelatedI just installed CentOS 5.5 on my machine and the installation appeared to complete successfully (it said it was successful). When I rebooted and tried to get into my new CentOS, my system completely locked up during the startup. According to the progress bar, it got stuck on the first-run configuration. I have not yet been able to boot into the OS. I am attempting to create a dual-boot system. I already have Windows XP installed on a separate hard drive. The GRUB loader works fine and I can choose either OS to boot into, it's just the CentOS won't finish booting. Windows is completely unaffected.Since I'm assuming the problem stems from the installation, I'll list the steps I followed.
1. Obtained the .iso image from a network drive at work (I am installing on my work machine). The image is dated May 17, 2010.
2. Burned the image to a DVD.
3. Booted from the DVD and chose to install using the graphical interface.
4. Checked the DVD. The installer verified that CentOS could be installed from it.
5. Picked my installation and keyboard languages.
6. Chose to create a custom layout for my partitions. On my second hard drive, I created the following partitions:
- Swap (8196MB, twice my system RAM)
- ext3 (100MB, mounted to /boot)
- ext3 (remaining drive space, mounted to /)
7. Picked my timezone (did not use UTC since Windows will handle setting the system time)
8. Set my root password. You don't get to know ;)
9. Did not choose to install any additional packages besides the KDE desktop. I wasn't sure what I'd need so I checked the option to customize later.
10. The installation than started and 15 minutes later, it told me it had succeeded and to remove the DVD and reboot.
11. Upon rebooting, I let the GRUB loader boot into CentOS (side note, I'd prefer if Windows was the default OS but that's something I should be able to Google on my own).
12. The startup looks like it's going fine until it gets to the first-run configuration, at which point the entire system locks up and requires a hard reboot. I've tried several times since and it always locks up at the same point.
For various reasons, I have to learn my way around CentOS. I have an old computer (P3) with Slackware on it. I threw in a second HDD that I had lying around and installed CentOS to it. I was figuring that I'd just decline installing GRUB or point GRUB to Slackware as the second OS and end up with dual boot.
The CentOS install, though, blew right past that part with offering me any options. It put a small boot partition on the CentOS drive and now the box boots straight into CentOS.
I've spent the better part of the day trying to get GRUB to boot the Slackware drive and had no luck, though I've learned a lot about GRUB error messages.
By the way, CentOS uses GRUB v 0.97.
Question: someone could point me to a reference.
Here's the output of fdisk -l on that computer (/dev/sda is a 4GB SCSI disk that was originally the boot disk for Windows 2000 server on that computer):
Code:
Here's the currentGRUB file. I added the section about Slackware. I've also tried pointing it at:

Slackware's LILO:
It's been six months or more since I used this computer. It's my experiment-er "play" computer and I had taken the HDD out to test a computer for one of the members of my LUG, so I can't remember exactly how I configured the LILO install, but, if I did what I usually do, I installed it to the MBR of /dev/hda. I have considered just blowing away LILO, but I'd be happier if I could just use GRUB to call LILO.
I'm running into a strange problem trying to change the service load or boot order on my CentOS 5.3 box.
The service in question is shorewall. When I go to my /etc/rc.d/rc5.d/, I notice that shorewall is listed a S27shorewall. I need it to start much later. So I run a simple command "mv S27shorewall S99shorewall"
I then restart the server. But after the reboot, something has reset it back to S27shorewall.
For those of you who like the background story: I need to change it to S99shorewall, because I need shorewall to start AFTER xend does all its stuff, as xend messes around with the underlying networking of the computer. The xend stuff was at S98 and S99...but I was able to successfully rename them back to S97 and S98, and the rename stuck. I've also renamed other service orders. Those stick. The only one that gets reset is shorewall, always back to S27. I have no clue how to tell what is causing the resetting...
I'm trying to create a CentOS based liveCD that mounts a NFS share and executes one script there. The NFS never mounts altough while logged I can mount it with the very same command that I use in the KS.
In the %post I have :
%post --log=/tmp/post.log --erroronfail
mkdir /mnt/nfs
mount -o nolock 10.23.1.1:/csc/RemoteHome /mnt/nfs
I added the --log in order to debug, but nothing is written in /tmp/post.log. I tried redirection on the mount command with >> /tmp/debug.log but this is not written. Maybe during the post sequence /tmp is RO ? Anyway, I tried with ifup lo, service portmap start in the %post, but doesnt change (I even have a service : command not found in the live cd creator output).

I have a pc where there was redhat installed, and I decided to put ubuntu in dual boot.The installation went ok, but now I can't log in with redhat anymore. RH was installed on a RAID partition, and I installed ubuntu on an additional HD.
Now I have two problems:
a) I cannot boot red hat, since there is no such entry in the grub
b) this machine had several users, that now cannot access it remotely anymore.
Below you can find the output of fdisk -l and the grub.cfg files, the old red hat one, and the new one created by ubuntu. Not that in any case I cannot reinstall redhat, since there are other people using the machine.

View 1 Replies View Relatedthe boot of my server is stuck at the message "GRUB"
I've allready tried :
chroot /mnt/sysimage
grub-install /dev/cciss/c0d0
but with no improvement. What else can I try?
OK Here's how it was:
1 I have 2 SATA drives - The first (/dev/sda) is a Windows only drive The second (/dev/sdb) has a Linux Partition + Swap (sdb1 and sdb2) of 40GB and the rest is an ntfs partition(sdb3)
I used to have Ubuntu on the Linux partition that nicely detected Windows, installed the bootloader on sda and correctly set up the boot options, everything "Just worked"!
Since I'm studying for RHCT I decided to wipe Ubuntu for CentOS, Centos also nicely detected an "Other" operating system, but it decided to install the bootloader to sdb. After a few minutes of frustration I realised this had happened and changed the BIOS to boot sdb instead of sda. While GRUB now happily boots CentOS, When I select Windows it just hangs.
I tried grub-install /dev/sda and changing the BIOS to boot sda, all I got was GRUB GRUB GRUB printed on the screen and then nothing happens.
get both OSes to boot? I suspect that windows doesn't like it if the bootloader is on a different drive to it's own partition.
UPDATE
It's OK I tried again to grub-install /dev/sda and changed the /boot/grub/device.map file and reversed the hd0 and hd1 entries, i then edited the menu.lst file and did the same, it now boots both OSes ok. The only downside is the nice CentOS background is missing in Grub now :)

View 10 Replies View RelatedI'm trying to install a dual booting machine with OpenSUSE v11.1 32bit and CentOS v5.2 64bit. I installed OpenSUSE first and allowed it to install and configure grub in the MBR and after that I wanted to proceed with CentOS v5.2. The installation went fine with two notable exceptions:- when I had to configure grub installation parameters, CentOS offered me only 2 solutions: either install it on the MBR of the first hard disk or not installing it at all. Other distributions are more flexible allowing you to install it in the boot sector of the root partition for example. Because I didn't want to ruin the existent grub onfiguration, I reluctantly accepted not to install it for CentOS assuming that I could manually configure the entry later in grub's menu.lst file.
- when I was presented with the options for software components installation, I've clicked on virtualization category/function because I intend to use the machine as a VMware host. There was no guidance on screen at that point and I blindly assumed that by choosing the virtualization function I would get necessary tools and drivers that will help me further on. It seems that this was a wrong move as you can see it below.
After completing the installation, I tried to search for a template or guiding on how the menu entry in menu.lst should look like but the grub directory was empty, not surprisingly because I've told CentOS earlier not to install it. Using the files in the /boot directory from the CentOS installation I tried to improvise a menu entry but it's not working. The boot stops with famous Error 13: Invalid or unsupported executable format. Using the file command to check what kind of files I'm trying to load as kernels I'm getting :

I clone an drive with CentOs 5.3 from a drive connected to ATA0 device 0 of an ATA controller to an identical drive connected to the same ATA contoller ATA1 device 0. No matter what I do it boots from ATA1 device 0 and I need to be able to control which one it is booted from. When I have puppy linux on one drive and CentOs on the other drive I can control the boot thru the system BIOS either way no matter if puppy is in ATA 0 or 1. So its not a BIOS issue. It appears (to me) to be a grub configuration issue. Since the 2 drives are clones they both have VolGroup00. I think grub loads from the last VolGroup00 found.
