and I've downloaded BT5 R2
I tryed to install it and suddenly in 99% an error message appeared saying that
"THE installer encountered an error copying files to the hard disk"

[Errno5 Input/Output error]

Did you check the MD5 or the ISO ? also please note that we have a VMware version available for download.

Check out if your burned the CD right. Even the amount of disk space allocated for the Virtual Machine.
Or try the BT5R2-GNOME-VM-32.7z.
