recently,i installed some packages on my kubuntu system. it was fine then. next day when i started my pc, it won't boot. it stopped at some point of booting. however when tried in recovery mode it started.
what could be the problem and how to fix it.
2.now when i've started my system in recovery mode, cdrom and usb drives are not automatically detected. i managed to mount cdrom from shell but i could not mount my pen drive. why is this happening? otherwise also how do i mount my pendrive. please give some links or something. i'm interested in knowing these things really work.
3.can we fix broken packages?? how?
4.some time back i tried to install ubuntu on my machine. during installation it asked abt the resizing the partitions. does the resizing affect other OSs on system.(i was not sure so i quit the installation)
PPLEASE DETAILED ANSWERS(OR LINKS)
