How To Edit the Boot Menu in Windows 7 Using bcdedit - January 5, 2010
I set up a single box to dual boot Windows 7 32 bit and Windows 7 64 bit. When booting up, the boot manager asks me which OS I want to start. The problem is that both the 32 bit and 64 bit versions have “Windows 7″ as the description. So… I get the choice of booting “Windows 7″ or “Windows 7″. This is even less useful than it sounds. To fix this, I boot up in to one of them and then open a command window running as administrator: start->all programs->accessories->right click “command prompt” and run as administrator. Next, I use a command called bcdedit. Run bcdedit with no arguments and it will list your bootable partitions. Each one will have an identifier inside curly brackets–something like {current} or {aa572c50-fa57-11de-9aae-9f4b2a2101ad}. To set the names you see in the boot menu, use bcdedit like this:
bcdedit /set {aa572c50-fa57-11de-9aae-9f4b2a2101ad} description “Windows 7 32 bit”
Just repeat the command and adjust for the other partition and you’re good to go.
