I did it bootable not INSTALLABLE. So ther`s how and what i did:

1. Downloaded all Slackware 11.0 and add to directory /home/ftp/pub/Linux/Slackware/slackware-current from -
ftp://ftp.mirror.ac.uk/sites/ftp.sla...slackware-11.0

2. Downloaded and installed ms-sys from -
http://www.slackware.com/~alien/slac...1.1-i486-1.tgz

3. Downloaded all 9 files and put them in /usr/local -
http://www.slackware.com/~alien/tools/usbinstall/

4. Then: cd /user/local and run command:
SLACKROOT=/home/ftp/pub/Linux/Slackware/slackware-current sh /usr/local/create_multipartboot.sh 3700


5. Then: cd /tmp/slacboot and write the usbhd.img
dd if=usbhd.img of=/dev/sda

To BOOT from flush is allright and works grate. But i need to INSTALL from USB flash NOT BOOT!!
For booting can use lilo - ofcourse
Anybody can help me?

Cheers!

If you keep the USB disk to FAT32 and keep all Slackware data, then you can install using that. Just select other while installing.

I mean, start the installer, there is an option.. from preexisting files on HDD or something like that.

I don`t have any preexisting HDD
My HDD is empty.

And the reason why a have to install from USB is because my cdrom is dead
