Stuck with Bootable USB?
 
I am in attempt to install Red Hat through bootable USB.
All I tried the following:
Code:
1. Logged into linux server DL380 G5 and plugged in with USB
2. # dd if=diskboot.img of=/dev/sda  command was executed
This made usb bootable.
3. Created a directory /mnt/iso  and  in the path /media/disk command

       
Code:

       
# mount –o loop RHEL-XXXXXXXXXX.iso /mnt/iso

was executed.
Rebooted Server.
4. Was successfully booted from the usb  and prompted the boot options & linux graphical was given.
Type of media was asked, without USB option and was unable to proceed further..
Any idea how to proceed further.

hi

there a number of guides on howto create bootable usb sticks.

I am not sure rhel is the ideal candidate...I think slax for usb is the easiest.

but in summary..for a single partition usb stick

get your media...mount it...it could be your existing sytem but that may be too large
create a new dir
cp the contents of the mounted iso into new dir
install a bootloader into usb mbr
and usb stick should have a bootable flag


umount usb and mounted iso
change bios to allow detection of usb hd...(not all bios allow it)
reboot to usb to test

I am suggesting again try slax for usb first

yes it uses lilo but you can make it grub

I just followed http://kbase.redhat.com/faq/docs/DOC-10553 and want to ask something very clearly.The DOc tells about following steps to make USB Bootable and at last refer to link for Installation Processes like FTP, NFS, HArd Drive ISO etc.
Say I have no OS Installed. And I want to install from HArd Drive. Is it possible?
If I have no OS running what could be option? How Can I make the Bootable USB install from USB only.

hmm I am not sure I understood.

to make an usb bootable stick from usb presumes the first one is already installed...then you insert the second stick and partition and install linux onto that.

as to your link...hmm I wonder if they have spotted that
"root (hd1,0)"

but when you set bios to boot usb...grub must detect usb device first so its really hd0

Please see my post here-
( http://www.linuxquestions.org/questi...mputer-709569/ )
Also-what platform are you working from Windows or Linux?
If in windows you may be able to install a distro my way-by moving files, etc by hand-that is copy&paste.
You don't need the terminal, even for the syslinux install-just folow that post above-However-I don't know how in windows you would be able to activate the "boot flag" for the USB.
Please explain more in depth what you wanna do?
