Install this: http://www.citadel.co.nr/readydriverplus/
Other solutions are useless 
My conclusion is that ReadyDriverPlus v1.1 gets stuck after changing anything in yout boot configuration. Even if you change “Time to display list of operating systems”. The result will be only blinking cursor and Vista will not boot (unless you manually select Vista->F8->Bypass Driver Signing Enforcement). You just need do uninstall and then install ReadyDriverPlus again.
Edit: Found better solution!!! See: this post.
1. Open command prompt (Win+R, then type “cmd” or just search “cmd”).
2. Type “bcdedit”. You will get a list of all items in boot menu.
3. Remember “identifier” field of the entry (system) that you want to remove.
For example: {cbd971bf-b7b8-4885-951a-fa03044f5d71}
4. The following command deletes the specified operating system entry from the
store and removes the entry from the display order:
bcdedit /delete {cbd971bf-b7b8-4885-951a-fa03044f5d71}
The following command deletes the specified operating system entry from the
store without removing the entry from the display order:
bcdedit /delete {cbd971bf-b7b8-4885-951a-fa03044f5d71} /nocleanup
5. After deletion, it there is only 1 entry left, boot menu will not be shown on next boot.
