Booting a New Kernel to Test

Toods · 11-08-2007, 03:51 AM

I have a dual-boot setup on one of my PCs and I am always nervous when building a new kernel to run Lilo and go through the 'dd etc' procedure to create a boot sector file for my Windows 'ntldr' to use to boot Linux.

Can I initially test the new kernel this way?:

Quote:

Build the kernel and install the vmlinuz-x.xx.xx and System.map-x.xx.xx in the /boot directory (which is in /dev/hdb7) and also the modules in /lib/modules/x.xx.xx.

Then boot the Slackware installion Cd to the prompt and issue: boot = /dev/hdb7 image = vmlinuz-x.xx.xx root = /dev/hdb7

Will that boot the new kernel and file system?.

Thanks,

Bill.

I don't blame you, why not use grub (instead of lilo) to boot both OSs?

Probably.

If you used grub, you can boot the kernel on the fly from the grub commandline, or edit an existing entry at bootup. Grub is more flexible in this way.
