From ALT Linux Wiki
ISO files can be burned onto CD-R/RW media or written to USB flash drive using dd(1); these should boot on more or less any PC starting from PII/K6 with 128M RAM (i586 versions) or AMD64-compatible one with BIOS or UEFI (x86_64 versions).
Predefined passwordless LiveCD logins: root and altlinux (graphical session starts automatically upon bootup).
One can choose locale with F2 on bootloader welcome screen; layouts are switched with Ctrl-Shift then.
Those wishing to install the OS permanently can use ALT Linux > Applications > System tools > Install to hard disk right-button desktop menu item.
