how to install Linux from iso image

[Maaz]

I have iso images of RHEL 4/5 and SuSE Linux 10 on /dev/sda7.
/dev/sda7 is reiserfs.

I want that I use the installation media to just boot the system, but want to install the OS on/dev/sda2 from the iso image reside on the same hard drive(dev/sda7).

Please help

I think you need to override the default installation option and select advanced option for "Install from locla dir(or smthing like that")

I have done this with SUSE.

> I have done this with SUSE
how ?
when I boot the system using sles 10 media, I got the following options

1, Boot from Hard Drive
2, Installation
3, Installation - APCI Disabled
4, Installation failsafe
5, Rescue
6, Memory Test
so what to do so that installation begins using iso image of sles 10 on /dev/sda7

Need help on rhel too.

For RHEL 4 it is quite straight forward. Boot using the "Boot CD ROM", select installation method as "Hard drive." The steps are very clearly mentioned in the manual at:

http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/x8664-multi-install-guide/s1-installmethod.html

For SUSE, boot using the "Installation" option, continue till you get an overview of the installation. Select "Add-On Products", specify the ISO images on your hard drive, CD 2, CD 3 or so on...

Redhat is ok.

I did as per your instruction, that is boot the system with the media, and then select the INSTALLATION, and then select the "Add-On Products", and specify the ISO image on the hard drive, after doing this excercise removed the installation media, but when Installation begins, it aksed me for the DVD.

Anyhow thanks

Hi Maaz,

For SLES 10, installing from the hard drive can be achieved by booting the installation from the hard drive & selecting the hard drive partition with the ISO image for the rest of the installation.

For this, you need to copy the linux & initrd images to a partition on the hard drive. Edit the grub menu to include the menu for installation. Here are a couple of links with more information about how to achieve this:

Note: Unfortunately, this will only work if grub is already installed, otherwise you would have to install grub manually & then go for the above method. :)
