Toshiba c655: chek cable connection! PXE-MOF:Exiting Intel PXE ROM. No bootable device--insert boot disk and press anz key

That error comes up when the computer cannot find the hard drive or any other device to boot from so it looks for a network booting program and when it cannot find that, the error shows up. REPLACE YOUR HARD DISK,

switch to boot devices (F2....F8,)do this as soon as you press power button.keep pressing to bring up bios disable all bootable items in list except cd rom.give this a try good look

First try this unplug from AC, remove battery, plug in try to boot normally. If that fails Open BIOS, Boot Order or the BOOT MENU, Boot from HDD first, and save changes and reboot, if that fails try a system restore/recovery.

Sounds like the hard drive isn't getting power,the data cable to the drive isn't connected,or the drive controller on the motherboard is toast(I'm a novice tinkerer,not an expert).

First - re-seat the harddisk and reboot the computer. If the computer does not boot up then reboot andgo into the BIOS configuration to see if the BIOS detects the hard drive. If itdoesn't detect the hard drive then it could be faulty.Then the hard drive needsto be replaced in the computer/laptop, Windows installed and the computer orlaptop's device drivers plus your programs etc. to get a functioningcomputer/laptop again.

your hard drive is corrupt or it is broken

Press F2 on boot. go to bios, ie insydeh20 setup utility. goto boot menu. select legasy in type. select your usb drive and hdd as a first boot device. save and reboot.

sounds like the HDD is playing up or a connection from the mainboard to HDD is loose!

check the boot sequence in bios
make sure that the first boot device is your HDD and disable the network boot
