Hi new here, have read around a fair bit and still having trouble activating my windows 7 ultimate. I have a triple boot system, winxp on disk 0 (3 partitions) winvista on disk 1 ( 3 partitions) win7 on disk 1 (3rd partition) xp is C: vista is X: win7 is W: I believe I'm using the vista boot loader, I recall having to use this when attempting a reverse dual boot between xp and vista so i used a program called "VistaBootPro" to uninstall the legacy boot lodaer and use vistas. Now, I've tried to use 3 of the available software activators, wow7, hazar's and hazars and orbits, each gives me the same issue. "There is no disk in the drive. Please insert a disk into drive device harddisk4 DR4" Even after this error maeesage the activators continue as if still working but after the reboot and checking activation is still required and trial period is still ongoing. I've searched long and hard for a solution and with litle luck, some of the activator writers suggest trying an alternative activator when facing the above error, but to no avail. I don't believe I have a system reserved partition as there is no mention of one in the disk management. I'd really appreciate any help with this, not sure what my best option is based on my multiboot system. I'd ideally not want to have to reformat and move drives around if possible.
