welcome to LQ i am not able to understanding what actuly you want
Installation can be done by three way
1) Optical media
2) USB
3) Network Boot

If you don't want to install from cd/dvd and USB then you can use PE kickstart network boot method to install the linux OS.

Well, i cant use Optical Drive (maybe virtual, but i only have access to windows PE and GRUB), also cant use USB.
I could use some network data, but i can configure LinuxPXE, because i already have a PXE server, can i start network instalation without PXE server from windows PE or GRUB?

You should be able to do it by first loop mounting the iso file of CentOS, copying it to a directory (best in the / (root) of the filesystem and then putting an entry in your grub.conf so you can select it on boot and install to a separate partition. I've only done this on a Linux filesystem partition. That's it in general terms but you've only posted general information.

So can i just:
1)Make a partition with GRUB
2)Copy the data from ISO installed to another partition
3)Boot the second partition and install the OS?

My main question is, will it install? The OS install files can be on a HD? Just unpacked?

Quote:
Make a partition with GRUB
If you mean create a separate Grub partition, that would be a start. However, in your initial post, you indicate you can 'use Grub', whatever that means. If you already use Grub as a primary or secondary bootloader, you could put the extracted CentOS files on a separate partition or on a Linux partition and put an entry in the grub.cfg, menu.lst or grub.conf file, whichever you have (grub.conf?).

If you already have a Linux partition, you would loop mount the iso, then copy it to a directory, I usually put it in the / of the filesystem and then put an appropriate entry in the grub.conf file. Usually you can modify the syslinux.cfg or isolinux.cfg entry for Grub. I don't know your partition structure. You could extract the files to the same partition you have Grub on if you create a separate partition for it. You would need to install to a different partition.

I've done this with several distributions, not including CentOS or Fedora, and it worked. Some distributions were problematic if I tried to install on the same hard drive, others were fine.

Quick question: Where are you that you can't access the DVD drive or USB ports? Is this a remote system somehow?

Hi guys, thanks a lot for help, that explain a lot.
So to specify what i have:
i have a windows partition with GRUB, i will find some tool for windows PE, to make 2 other partitions, and i will copy the instalation files to one of them, and install the OS on the third one, hope it works
Regarding why i cant use USB/DVD, yes, i am in a remote location, i want do prepare it so that it will do zero touch instalation with starting from SCCM, and then installing from kickstart (i have kickstart already prepared, i just need to boot an iso from the HD).

I will try this today, if you have any more ideas for me, i will be happy to listen to them.

Once more thanks alot for all answers, the people at SCCM forum were not that helpful.
