Can I install Jessy from Rescue? (4 replies)

Hi all

My current Debian installation on the Goflex (with a SATA harddisk, sda rootfs, sda2 swap, sda3 data) is showing its age. There are a couple of corrupted sectors and i should run e2fsck, but since it is mounted and rootfs I cannot do that. "touch /forcefsck" didn't help.

I'm willing to perform a fresh install, but am a bit lost where to start. How do I get Jessy on sda1? Can I install it from Rescue? How do I boot into Rescue while the sata disk is plugged in?

Thanks for help!
