Post Problem booting SystemRescueCD from multiboot usb
Hi

I created a multiboot USB with Knoppix DVD and SystemRescueCD using MultiSystem, which says it supports both (http://liveusb.info/dotclear/index.php?pages/os). For those of you not familiar with it, MultiSystem basically installs the liveCD onto the USB and adds the grub menuentry. Knoppix works fine. The problem is when I try to boot sysreccd, it complains about not being able to find sysrcd.dat and kicks me to a minishell. I've confirmed that it is not detecting my USB for some reason. /proc/partitions shows only sr0 and sda, sda being my hard drive, and it only attempts to mount /dev/sr0 and /dev/sda[1-6] when it's looking for sysrcd.dat

The menuentries in grub.cfg:

Code:
menuentry "SystemRescueCd 32bit" {
linux /systemrescuecd/isolinux/rescuecd rootfs=/systemrescuecd subdir=systemrescuecd dostartx setkmap=us scandelay=4
initrd /systemrescuecd/isolinux/initram.igz
}
menuentry "SystemRescueCd 64bit" {
linux /systemrescuecd/isolinux/rescue64 rootfs=/systemrescuecd subdir=systemrescuecd dostartx setkmap=us scandelay=4
initrd /systemrescuecd/isolinux/initram.igz
}


I'm not too familiar with linux kernels and modules, but maybe it has to do with the kernel not loading usb device modules or something? Are the boot options right (rootfs, subdir, etc.)?

Work sysrcd with its own USB installer?
Maybe the multiboot driver "lock" the USB hardware.

try "dmesg|grep usb" from the minishell to get more informations.
lsmod shold show the module usb_storage.

I think you dont need rootfs because all partitions are scanned.

lsmod | grep usb shows nothing. Is there a way to force grub/systemrescuecd/linux kernel to load usb_storage?

Post Re: Problem booting SystemRescueCD from multiboot usb
I sort of got it working now. My laptop has two USB 3 slots and one USB/eSATA combo slot. SystemRescueCD boots when the USB is in the USB/eSATA slot. Some compatibility issues with USB 3 slots? Anyway, after booting, I try to mount my external hard drive (plugged into one of the other USB 3 slots), and the drive mounts as read-only. I plan on using SystemRescueCD to backup to my external hard drive, so I still need to get this to work. How's SystemRescueCD's support for USB 3 slots?

The usb 3.0 driver xhci-hcd is in sysrcd.dat but not in the initrd.
You can just for testing save this module at a accessible place and load it from the minishell.

A workaround is to store sysrcd.dat and sysrcd.md5 on a harddisk partition in "$subdir".

About the readonly filesystem: Used you mount for a NTFS formated partition? Using ntfs-3g instead of mount helps.

Looking at this http://www.sysresccd.org/forums/viewtopic.php?f=14&t=4137, I'm guessing it is a problem with USB 3.0. As SystemRescueCD isn't viable for my back up purposes, I picked up CloneZilla instead, which works perfectly. I look forward to when sysreccd supports USB 3, it has a bunch of useful tools.
