Hello, VL community. This post is just to inform about a feature that it was immensely helpful to a linux newbie.
I had to install some linux on an pretty old compaq laptop. The laptop has a seemingly working CD-ROM unit, which boots iso perfectly, but later on installer (not just VL, any other distro I tried) doesn't recognize setup cd/dvd anymore. With other installers it was game over (not really suprising, because obviously the cd-rom is not completely dead...), but when VL doesnt succeed with mount it is giving option to run setup also from iso (same as was burnt to cd), which is copied to a normal usb flash. I know that USBs can be made bootable, but this old computer doesnt seem to have this possibility.
I do not know why this feature is present in VL setup and I am quite sure there are some other alternatives to install system (install from hard drive or network) but for my unique circumstance it was very helpful.
