I have a Dell Inspiron 1564 laptop. my harddisk partitions are not visible when i try to install OS.
In the BIOS the HDD size is 10GB only. But my laptop had 320GB.
on boot it shows:
PXE ROM "Media test Failure- Check cable"
Operating system not found.
on running dell diagnostics it shows:
Hard Drive DST Short Test - Test Results: Not Applicable.
Also, If i insert a live cd, the partitions i had are not visible. When i am trying to install a new copy of OS, there is no partition to select.
