Question emergency ask for help on booting not from hard disk


Hi,

now I explain exactly what I need,

I have a fc10 on IBM architecture , I need to boot from a CD-ROM or USB drive , and I need just start-up process to use it, it means that T just want that this external drive mounting the actual root partition and loading the kernel image (exactly as what i need for booting process),
and I have this problem that I've not available vlinuz and initrd.gz file in /boot path! what must I do?

I've written a bootable cd-rom as this way:

Code:
 cp /boot/{vmlinuz-2.6.27.5-117.fc10.i686,\
initrd-2.6.27.5-117.fc10.i686.img} syslinux-3.72/core/isolinux.bin bootcd
and then for producing iso file:
Code:
 mkisofs -o bootcd.iso -b isolinux.bin -c boot.cat -no-emul-boot\
 -boot-load-size 4 -boot-info-table -j -hide-rr-moved -R bootcd
but , when I boot from CD_ROM ,it asks for as "boot>" that I try vmlinuz , that wasn't any acceptance to it,

I also need to have dual boot with winxp, so if it need to edit the grub.conf file or if an other file please guide me how can I and what changes, thanks



please help me as soon as possible,because Iĺl be confused more and more!!

CD-Based Linux?

I'm not sure what you want either.

If you use a CD-based distro, like Knoppix, you can mount your hard-drive partitions, and access the data there.

If you want to initiate boot from a CD, but actually use the hard-drive Linux kernel in /boot (on the hard-drive), then I believe you can give parameters on several of the CD-based Linux distros' command lines.

thatś right!
before I must say that I have 3 os: vista,xp and fc10 on my /dev/sda in this sequence that : sda1 partition for vista system files and sda7 is for fc10 root partition system files, as this explained image:

Code:
   Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1        1040     8345600   27  Unknown
Partition 1 does not end on cylinder boundary.
/dev/sda2   *        1040       10178    73408135+   7  HPFS/NTFS
/dev/sda3           10179       30401   162441247+   5  Extended
/dev/sda5           10179       17345    57568896    7  HPFS/NTFS
/dev/sda6           17346       23873    52436128+   7  HPFS/NTFS
/dev/sda7           23874       25785    15358108+  83  Linux
/dev/sda8           25786       26295     4096543+  82  Linux swap / Solaris
/dev/sda9           26296       28300    16105131   83  Linux
the following is my grub.conf:
Code:
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You do not have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /, eg.
#          root (hd0,6)
#          kernel /boot/vmlinuz-version ro root=/dev/sda7
#          initrd /boot/initrd-version.img
#boot=/dev/sda
default=0
timeout=5
splashimage=(hd0,6)/boot/grub/splash.xpm.gz
hiddenmenu
title Fedora (2.6.27.5-117.fc10.i686)
	root (hd0,6)
	kernel /boot/vmlinuz-2.6.27.5-117.fc10.i686 ro root=UUID=a1baee87-117b-479c-bb33-57d4bce83871 rhgb quiet
	initrd /boot/initrd-2.6.27.5-117.fc10.i686.img
title Other
	rootnoverify (hd0,1)
	chainloader +1
now if I prefer to initiate boot from a CD, but actually use the hard-drive Linux kernel in /boot (on the hard-drive), what parameters must be edited?

thanks in advance of your attention
