General :: How To Write Grub On Another HD
Feb 5, 2010
I have XP on the boot HD, Ubuntu 8.04 on the other HD, and grub on the MBR of the Windows side. Then the Windows HD went bad and I need to get grub onto the other side so I can change the boot sequence to what was the second HD (the Linux one) and abandon the Windows side. Booting from a live CD is no problem, but I can't figure how to install grub onto the Linux side, which has been partitioned. I know where menu.lst is, and have backups of it as well.
Is this something that needs supergrub, or can a simple write to the proper place be done in a terminal window?
If switching the boot sequence is not enough (don't see why it shouldn't be) then I can also switch the jumper configurations on the two hard disks. But I don't think that should be necessary.

I am trying to install grub in MBR. I have working configuration on my root partion. I tried "grub-install" on MBR but gives me some warning.
Code:
/usr/sbin/grub-install /dev/sda
WARNING! You are trying to invoke the unsupported grub-install script with a parameter. To really do this, call grub-install.unsupported. You should rather call "yast2 bootloader" or create configuration files appropriate for the intended target. Also I tried it from Yast but still MBR has Chamelon boot loader.(I have chamelon boot loader, I want to overwrite my MBR with current grub configuration on my root partition.)
I tried using grub-install.unsupported but it did not work either. it says: /dev/sda does not have any corresponding BIOS drive.
I tried grub-editor (kde module) to do the work, but it gives me error: grub-install returned and unknown error exit code 1.

I made a clean install of opense Suse and by mistake I overwrited the menu.lst (because of the restoration utility). As a result I have the grub error 15 : file not found, and tried everything I could think.
Grub is installed on the MBR and boots from the extended partition. The new openSuse is on sda8, there is an old openSuse on sda4 but xorg is broken. I can boot on Windows, and sda4, but not on sda8 menu.lst

Someone sees what's wrong in the menu.lst ?

I have a windows 7 hard drive as Sda0 and have a second hard drive as Sdb1, which is where I want to install OpenSuse 11.4. Now here is where I am not sure on the install, so I don't screw my self up. I have 100mb partition on sda0 that windows 7 is using, do I enable grub or have the boot write to MBR?

I have been following this tutorial [URL]. When I get to the end of the installation and try to install GRUB to the /boot partition I have set up it throws a fatal error at me. No explanation other than it can't write to the specified location. I double checked all the partition settings which were the same as the tutorial then skipped the GRUB installation and finished. The only thing I can think of that might be wrong is that the 250MB partition size specified for /boot in the tutorial is too small.

I got a new Sony Vaio Z and try to install Ubuntu on it. The laptop has got two 64 GB SSDs setup as a RAID 0 array. [URL]. As the configuration is done in the BIOS, I assume it's hardware RAID. [URL]. The problem is that - no matter what I try - the installers are unable to write the GRUB loader on the hard disk. I tried both, standard and alternate installer (9.10 / 64 bit), and both failed at that point. Not a really error message, it just says "cannot write GRUB boot loader".
I also tried two different scenarios:
- Ubuntu beside Windows (shrinked the partition for that)
- Ubuntu on the empty RAID

my Setup is Fedora 14 x64 + radeon hd 4830 i've downloaded .run package from ati site with latest driver for x64 systems. installed it, but didn't edited grub.conf becouse i didn't understood anything there (probably didn't spent enough time to get things understand) Now i've lost possibility to enter my Fedora system. during boot it lost it's modern blue boot screen (with filling drop), it was replaced by standard old boot screen with triple-color stripe. after this boot screen monitor start blinking going on and off. and on last step i'm getting "Fedora 14 boot bla bla bla something" on screen. nothing works except Ctrl+Alt+Delete. system reboots showing successful daemons shutting sequence. How can i edit grub menu from initial grub screen is it possible to it's own 'e' option or 'c' from grub command line?

I installed Debian on my PC and then installed Ubuntu. This worked fine and I could dual boot between the two. The PATA disk was /dev/hda on debian and (I think) /dev/sda on Ubuntu. I copied the entire disk to a sata disk using dd from knoppix and put the PATA one to one side. Now the Ubuntu comes up fine but when I boot debian, it complains about references to /dev/hda1, which is present in grub - root=/dev/hda1. Debian now expects sda references rather than hda references. How do I persuade Ubuntu to write /dev/sda1 to the bootloader rather than /dev/hda1 using grub-mkconfig?

I am using kernel 2.6.32.21, and my hard disk is West digital WD10EARS-00Y, 1TB. This disk is just for data, I made 2 partitions on it, each has half. And I have another small disk for system. I am using ext3.
this is my fdisk /dev/sdc
Device Boot Start End Blocks Id System
/dev/sdc1 1 60800 488375968 83 Linux
/dev/sdc2 60801 121601 488384032+ 83 Linux
[Code]....
I ran some dd to test the write throughput on /dev/sdc2. If I run it in /data2, I got around 70MB/s. If I create some directory, say /data2/dir/, and run dd again, I might get 60MB/s. Sometimes I still get 70MB/s, sometimes I get 60MB/s, differs for directories.
I wonder if this is because the allocation policy of file system, ext3, or this is from my hard drive?

I just did a fresh install of Fedora 11 and added Raid 1 following this tutorial: [URL]
Now I see the filesystem when I open 'Computer' in the GUI, and I open it and see 'lost+found', but i can't write to the drive. The option is simply greyed out. And when I view Properties on the drive and go to Permissions, it says 'The permissions of {driveid} could not be determined.'

I want to keep a trace of the URL I visit, so I use a command line like this:
tcpdump -ien1 -v -X 'tcp port 80' | sed -nl
's/^.0x[0-9a-f]{4}:.{43}(.)$/1/p' |perl break.pl |perl -pe
's/(GET|POST).(.*?).HTTP/1....Host:.([a-zA-Z._0-9-]*)../"
BEGURL
[Code]....
I also tried redirecting stdout and stderr to /tmp/out, it's still empty. The file has write access. I have no idea what it can be. Is there anything else than stdout and stderr?

I am using OpenSuSE 11.0
KDE 3.5.9
Konqueror
I was able to copy 227 images to a brand new 2GB memory card and I am only using 8% of the card and now I can't write to it anymore?
Code:
Filesystem Size Used Avail Use% Mounted on
df -h returns this : /dev/sdd1
1.9G 136M 1.8G 8% /media/disk-2
This isn't the first time this has happened either. Just the last couple times I didn't really care enough to pursue it. But now I am trying to load a card for my daughters digital photo frame and I can't because now all of a sudden I can no longer write to the drive? The exact error message I get is: "Could not write to /media/disk/image.jpg" and when I try to create a new folder, I get a disk full error message? How in the heck is this possible when I am only using 136MB of 2GB of capacity?
