my laptop(Dell Inspiron - 1525) while booting says hard disk not detected.....it all happened suddenly ..nothing was wrong with my hard disk as well...my notebook is 6 or 7 months old (WDC WD2500BEVS-75UST0).
the mesage while booting says.......Cannot find a bootable device. I don't think its the controller as I connected another harddisk to the same notebook and no problems were encountered. However, connecting my harddisk to another notebook came up with the same message: Cannot find a bootable device.
Any suggestions? I really need to recover my data.
This problem lies within your BiOS.
You need to go to the Sata settings and change the setting to ATA. You will have to change the cache module to off before you can change to ATA. Once you have done that you can load a new O/S or reboot your old OS using recovery.

The exact same thing has occurred to my 1525 also. about two weeks after I bought it the same msg"no bootable device. I have taken it in to three different Laptop r.s and all have returned the same diagnosis and cure: get a new hard drive and start over. I am hoping that you have come up with a different answer? If not I just got the exta cash to get a new part and will be going ahead with that. good luck
