Hi guys,

I've slackware 64 bit installed in partition sda1.

The BT4's installation is in sda3.

Now, if I install GRUB from BT4, I can boot BT4 without problem... but I can't boot Slackware (I can see it, but if I start nothing happens).

Same with Slackware, after installing LILO and added BT4 I can boot slackware but not backtrack (this time, I start BT and it hangs on USB devices, I have nothing attacched and it seems like it stops at the card reader).

I've acer aspire 5735z

I used BT for a long time without problem, this is the first time that I dual - boot.

Hope you can help!
