similar to: Removing Dual Boot

I am still dead on my corporate system, and the XP boot CD I brought won't boot. And so far I have not found anyone here at the IETF meeting that happens to have one in their bag of tricks... So I found instructions on doing this in Ubuntu: http://www.arsgeek.com/2008/01/15/how-to-fix-your-windows-mbr-with-an-ubuntu-livecd/ I have my Centos install CD 1 of 6 that gets me into rescue.

I tried to install CentOS 4.4. This was on a machine where I've got Windows XP on the first partition (hda1). CentOS, like most of the distros will automatically install Grub in the MBR unless you tell it not to. In fact it will wipe the MBR first pretty early in the install. Here was my problem. During the install, the second CD had some sort of read issue. So I had to abort the install

hello all, I have a setup that is raid 1 and put the mirrored drive back in and now it is still showing as degraded saying: raid1: raid set md6 active with 1 out of 2 mirrors with this message on all the raids.i know i am wrong by saying this but i thought putting in the driving and rebooting would start the re syncing itself. what do i have to do to add this back in, i am so confused with this

Oh, Boy. I am in trouble now.... I just installed Centos on a USB drive on my corp notebook. To not TOUCH my corp drive. I spent time with the drive partitioner to make sure that nothing was done to the internal hard drive... Well I missed something and I overwrote the encrypted bootloader on the hard drive. Now what? Can I rescue things? I am leaving for my flight in a couple hours to

Is there any tool for analysing the MBR on a computer? I know one can just dd it and see roughly what it contains. But surely one should be able to work out the exact content of the MBR and the neighbouring sectors read at boot time? I had a difficult day, probably due to my ignorance, which would have been solved at once by such a tool. I had taken one of three hard disks out of my home server

Hi, I have a laptop with 2 hard drives. The first has Fedora 20 (no windows or anything else) and the second is unused. I would like to install CentOS7 on the unused drive so I can dual boot with the choice of the 2 OS's on the Grub menu. I am comfortable in partitioning drives and installing Linux distributions. I am afraid I may mess up the MBR and/or set up Grub incorrectly so I

I'm trying to get Ubuntu 10.04 LTS Server to install and run (boot) on a USB Flash Drive. The actual install process works without a problem and will complete without an error. It by default wants to install grub and place it on the MBR. Doing this completes the installation but my BIOS will not boot the USB disk. My partition table at this point looks like: /dev/sda1 - 8 GB - EXT4 (Ubuntu)

I'm having trouble installing CentOS-7 on my HP MicroServer. I've tried with KDE LiveCD and Netinstall (both on USB sticks), and now I'm going to try with the DVD ISO. But I want to be quite sure I can return to CentOS-6.5 if things go wrong, so I'm wondering what precisely I need to copy (eg the MBR and a bit more) so that I could get back to things as they were. Is this

Hello All, I have an off topic question about rsync and was wondering if i can get some kind person help with it. I have two servers with each server have three same directories on them /dir1/ /dir2/ /dir3/ . How would i achieve this by using rsync? I have tried rsync -avrt --delete server_ip:/dir1/ /dir2/ /dir3/ /dir1/ /dir2/ /dir3/ this does not do anything except give errors. Someone on IRC

I ran into a problem when using grub-install experimentally in what is obviously a foolish way, since I was unable to boot the machine afterwards. I got round the problem, as I shall explain, but I'm still interested to know why the problem arose. Having added a second hard disk to my CentOS-6.5 server, as an experiment I gave the command grub-install /dev/sdb after checking (with fdisk)

Hi, I have this dual boot Vista-CentOS. I have one NTFS for Vista, and three for CentOS. I boot to both OS through grub. Unfortunately, I'm going to need the CentOS space for Vista :( :( :( So my question is: if I remove the CentOS partitions *from within Vista* with its tool for it, will I be able to still boot Vista ? Is grub going to disappear ? If so, will Vista replace it for its

Do most people today have /boot on a separate partition, or do they (you) have it on the / partition ? -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin

Yes, these are my thoughts as well. I think the jump from GRUB to the isohybrid code on the logical partition is working fine, but when the isohybrid code is trying to jump to

You probably mean this line: memcpy(mbr, &isohdpfx[hd0 + 3 * partok], MBRSIZE); The indize do not apply to bytes but to byte arrays of size MBRSIZE. extern unsigned char isohdpfx[][MBRSIZE]; (hd0 + 3 * partok)

I used syslinux to make an external usb hard drive booting up "system rescue cd" from a FAT primary partition. The procedure I followed was setting on the boot flag on the FAT partition and copying the content of the iso image to it and renaming isolinux to syslinux wherever needed. I then unmounted the device and ran "syslinux -d /syslinux/ -i /dev/sdxn" where sdxn is the

I'd like to take advantage of the small, compressed Linux systems such as Knoppix or BeatrIX, but I can't have a CD rom on my system. (A project's marketing requirement.). So I figure I could use something like SYSLINUX or ISOLINUX to do it for me, but there is some magic in the process (the sequence of booting) that eludes me. 1/ mbr (from SYSLINUX) installed on hard drive... and
