I think this is an error caused by what i think to be the real root dilemma, when my hard drive is physically set as the first boot device, the CD-rom drive is undetected by the BIOS, and vis versa, although when the CD-rom is set as the first, im able to boot into the windows 7 install CD.
Im not sure if this is due to my BIOS being outdated, or what could cause this-but i believe its causing the cd to not see the drive as a boot device, or a win-7 installation. Any help would be greatly appreciated, I have scoured these forums, and worked for hours on my own to no avail. All suggestions are appreciated. Thank you for reading this small book i seem to have typed. I tried all of the solutions listed above, and again to no avail. What you are doing here is jump-starting the Repair by preceding it with bootrec commands which are automated in Win7 Startup Repair, but which may not be completing if it is malfunctioning due to OS corruption.
Backup a Win7 image externally so that you never have to reinstall again. All of those bootrec and bootsect commands are automated in Win7 Startup Repair, along with dozens of other tests and fixes which require it sometimes to be run up to 3 separate times with reboots to complete MBR repairs. However, as implied earlier bootrec can sometimes jumpstart the Repair utility if no installation is found to begin with. Some installations cannot be repaired, especially ones corrupted by GRUB.
I will often go on running Startup Repair anyway and sometimes get it running but at some point you may want to cut your losses, wipe your HD and clean reinstall the OS's to separate drives if at all possible. Choose a proper method to search for the deleted boot partition and click "Next". Step 5. Then you can choose the deleted system drive and click on "Proceed" to recover the lost boot partition. I sincerely hope you will get a proper method according to your special situation.
What does it mean by "no bootable device"? Why does PC say no bootable device? Method 1. Remove and connect back all hardware components Method 2. Check boot order Method 3. Reset primary partition as active Method 4. Check internal hard disk status Method 5.
Remove and connect back all hardware components At first, you can completely power off your computer, remove all hardware devices, then put them back all properly. Check boot order An incorrect boot order could mislead your computer to boot from an unbootable hard drive, then the "no bootable device found" will occur. Reset primary partition as active The partition where the operating system is installed is called as primary partition.
Check internal hard disk status If the internal hard disk has some disk errors, the "no bootable device found" error might pop out during Windows startup. Still Need Help?
