i disconnected the power cable to the hard disk and tried to boot,but it booted (through ubuntu live cd).What might be the cause for this problem?I need ur help
Does your Seagate hard drive have an OS installed? INstalling a new hard drive includes loading the OS as well. Otherwise, you have an empty file cabinet. Good Luck
this hard drive might be damaged. but before getting rid or it. check the jumper settings on the drive. if 2 drives are set the same the bios might ignore them both.
It could also be the power supply, at one point I had to upgrade to a higher wattage power supply in order to support it running another piece of hardware (video card). All of the above options are possible, but if you have a low wattage power supply that could be something to check on also.
You will have to do one of the following: 1] In BIOS Tell you computer which drive to boot from 2] If it's a new hard drive and the only one in your PC then you will have to install an operating system such as Windows
If you disconnect the power cable to your hard disk in which your system disk is located, for sure, your system will not boot, it will boot only if you have inserted a bootable cd or other drives, the system will not also detect your hard disk., there will be no activity to your hardisk, because there is no power even the interface cable is connected. Reconnect only the power, when the system has shut down and power ac cable also disconnected.. If your hard disk is new, you need to have a bootable installation cd (such as windows xp), it will boot to the cd, then you can create partitions (if you want), to the new hard disk, then instllation process will continue, just follow if you are prompted..(note that new hardisk normally not formatted and it will not boot or run without installing operating system program on it)
