what is the kernel or boot loader of ubcd ?
hi i trying to load ubcd from usb hdds.
so i tryed isolinux.exe
and it works.
but i encounteren some problems after that.
now i can see ubcd menu.
but when i try memtest it fails. and i cant see any file on memtest.iso using winrar.

and when i try to boot ubcd.[xp sp2] it waits with a blinking caret long time. and i guess it newer ends [i didnt wait more then 30minutes]
because someting on memtest too fails.


so if someone knows how to do the rest. and can help. it'll be good.
thanks.

Where did you find isolinux.exe? AFAIK it doesn't exists.
For booting from a USB HDD you need to partition a partition of the HDD in FAT16 or FAT32 and you need syslinux (for partitions formatted in FAT16 or FAT32) as bootloader instead of isolinux (for CDs)
Copy all the files which are inside the iso on it.
Download the last syslinux version: http://syslinux.zytor.com/
Extract /win32/syslinux.exe from it.
Open the command prompt (cmd.exe)
Drag and drop the syslinux.exe file to the command prompt.

There is also a script in /tools/ubcd2usb that you can use. It is designed for USB thumb drives so I don't know if it works for USB HDD. The script does format your hard drive, so you loose anything that you have on the drive.

Search the forlum for syslinux and you will find a lot of posts.
