Hello experts,

I have  Linux server which is booted via RHEL DVD and it gives me the REDHAT Linux installation screen with 'Boot:' prompt, I want to know the command to proceed with normal boot instead of RHEL Installation at 'Boot:' prompt.

Please take look the snapshot.

I don't want to remove the DVD and reboot the server. I am curious to know the alternate way of doing it.

If you want to customize the boot options for a particular option, press the Tab key. To access the boot: prompt at which you can specify custom boot options, press the Esc key.

The only alternative would be to have the BIOS changed to look at the hard disk first before the CD/DVD player.

I want to know the Boot: prompt command to boot directly from harddrive, not via altering the BOIS. Please help me with the command.

I've checked the Anaconda manual and I can't find a command for booting from the local hard drive so I'd say the only way is to remove the DVD and reboot the server, or change boot order in the BIOS.

Only way I can think of is creating a custom RHEL DVD that has a modified boot menu. Same as modifying the boot menu on a harddisk based installation. Since you have the standard RHEL DVD there is no possible way to boot from harddisk as the original DVD is meant for setup or recovery, it will not boot automatically...

Hi, as I don't own a RHEL DVD, I went along with a Fedora DVD, modified the boot menu but upon starting I got an isolinux checksum problem. I have to do some further investigation on that. What I did was mount the .iso image of the DVD using magiciso and modifying isolinux.cfg (menu default).

F11?

You could install multiboot on a thumb drive and configure multiboot menu to boot either hte local HD/cdrom or iso on the usb stick.

Pressing the BIOS F11 key will not work as the system is booted from DVD already.
