I have been Running WIN7 Pro on my Intel D945GTP MB for quite a few months. All was working well. I shut it off recently and when I turned it back on, I got a message that says "No bootable device -- insert boot disk and press any key This is all I get. Now of course I went into the BIOS and checked my settings and Both the 320gb and the 500gb Seagate Barracuda Hard drives are there, listed in that BIOS. All the settings were correct. These are SATA drives. WIN7 loaded on the 320gb drive and the 500gb used for data storage. I went to the Seagate website and downloaded their Seatools for DOS, created a DOS readable CD, installed that CD in my drive and tested Both HD's. Both HD's are seen by the test program (in DOS) and both tested OK! I just did the short test but Seagate says that is OK. On this system I am running 4 gb of RAM and a 3.4 GB Pentium D dual core CPU. I don't get it. BTW, just on a whim, I tried doing a fresh install starting with the Install DVD hopeing that that method would at least read the HD's but nope! The install process only sees one of the HD's but can't seem to install to it. Any ideas will be appreciated. Thanks, jeroldo

Hi, Based on my experience, the error message is caused by corrupted boot system file in MBR. To resolve this kind of issue, you need repair the boot file. The following methods are optional: 1. Boot in WinRE to check the hard disk using CHKDSK utility. 1) Please insert the Windows 7 DVD and reboot the computer. 2) When we are prompted to press a key to boot from the DVD, please press Enter or the space bar. 3) Click "Next" and click "Repair your computer". 4) Please highlight "Windows 7" and click "Next". 5) In the dialog box titled "Command Prompt". 6) Type: CHKDSK /F. 2. Insert the Windows 7 installation disc to perform a Startup Repair. Note: Please ensure that the DVD-ROM is the first booting device. 1) Please insert the Windows 7 DVD and reboot the computer. 2) When we are prompted to press a key to boot from the DVD, please press Enter or the space bar. 3) Choose your language settings, and then click Next. 4) Click Repair your computer. 5) Select the operating system you want to repair, and then click Next. 6) On the System Recovery Options menu, click Startup Repair. Startup Repair might prompt you to make choices as it tries to fix the problem, and if necessary, it might restart your computer as it makes repairs. If Startup Repair fails, please use the Bootrec.exe tool in the Windows Recovery Environment to troubleshoot and repair startup issues in Windows Vista or Windows 7.
