I have win7/win8 installed on my pc. Recently re-installed win7 on the first partition, now i no longer have the option to boot win8 on the second. How can i repair this?
You can do a start-up repair using the W8 DVD, if none use the W7 DVD. Sometimes one will have to do this 2x!
Get a small program called EasyBCD add the proper for you your Windows 8. mine 3x boot reads as follows: Windows 7 Ult (C:\Windows) Windows 8 Pro (F:\Windows) Windows 8 Ent (G:\Windows) save then reboot an you will have options to chose:
to get back win 8 boot loader: Run command prompt (SHIFT+F10) from the Windows 8 installation medium. bootrec /fixmbr - update the main boot record bootrec /fixboot - update the boot sector of the system partition. bootrec /scanos - add known OSes to the boot configuration data bootrec /rebuildbcd -rebuild the boot configuration data.
I have the same dual boot with win 7 and win8 with EasyBCD(Great tool by the way). When I start up get my boot screen with win 7 and win8 start win 7 and shutdown everything went fine. When I choose Win 8 also boot normal, but when I shutdown Win 8 with the shutdown button (on the right side of the screen), and start again I get no bootloader screen. I only get the normal bootloader screen when I choose the Restart button. I readed somewhere that the shutdown in Win 8 is some kind of hybernate, to startup quicker ??? greets from Holland UPDATE : Found the settings in powercontrol now It boots both OS
