Installing CentOS from the Internal hard disk
  

I am having an old box by using CentOS. I have created a partition on the internal hard drive as a installation partition. I have plugged the hard drive and created a small NTFS primary partition at the end of the hard disk. I am using unetbootin-windows-494.exe and a copy of the CentOS installer for the partition. Now I am getting an issue with the MBR of the system. What should I do so that I would be able to load the MBR for the installer. Let me know if you are having on this particular matter. Thanks a lot in advance.

Re: Installing CentOS from the Internal hard disk

I have done the following steps which is working.
  • You should mount the hard disk which would be used and create partition of 1 or 2 GB.
  • You should download the MBRfix from official website and use the following command.
Code:
C:\> MbrFix.exe /drive 1 fixmbr /yes
  • You should copy the isolinux and LiveOS the CentOS ISO file.
  • You should edit the boot.ini file from the notepad software.
Code:
[boot loader]
timeout=30
[operating systems]
C:\grldr=Start GRUB
  • Now you should launch the c:\boot\grub\menu.lst and enter the following line
Code:
 title Install Linux
kernel (hd0,0)/isolinux/vmlinuz0 
initrd (hd0,0)/LiveOS/squashfs.img

Re: Installing CentOS from the Internal hard disk

Well I have used the unetbootin and done a full standard disk install on the computer. It seems to be creating following files.
Code:
unetbtin.exe
ubnldr.mbr
ubnldr.exe
ubnldr
unetbtin
it is also changing the boot.ini file on the computer.
PHP Code:
[boot loader
timeout=15 
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systemsmulti(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect 
C
:\ubnldr.mbr="UNetbootin" 
Now I have placed the LiveOS, isolinux on the installer partition on the computer of mine.

Re: Installing CentOS from the Internal hard disk

Looking at the requirement of yours I am suggesting the following instruction which you can use to get the requirement of yours.
  1. You have to mount the hard disk and you should create the partition by utilizing Gparted.
  2. Now use the unetbootin and create full standard hard disk install on the computer.
  3. You should reboot the computer after modifying the boot.ini file.
I am hoping that the instruction which you mentioned over here would be helpful to meet the requirement.

Re: Installing CentOS from the Internal hard disk

The most important thing which I want to tell you is that you should copy the ISO file on the Linux. You have to see that the you have placed the file on the FAT32 partition. Otherwise the distros which you are looking to install will not have support for read and write. Some of the distros you need to require copy on the root of the partition. If you don?t do this then set up would not be able to detect the same.

Re: Installing CentOS from the Internal hard disk

I recommend that you should use the Winrar in oder to launch the ISO file on the computer of yours. you can found the file at the isolinux directory. I have found that the different distros would needed different locations. Also you should use the below mentioned piece of the command.
Code:
#ADD NEW ENTRY#
title Install Linux
root (hdX,X)
kernel /distro/Linux_kernel
initrd /distro/Ram_disk
Restart the computer and choose ?Install Linux? from the grub.
