Not sure if this belongs here, so if not hopefully its moved to the right location or someone can point me to the right fourm. Got a compaq computer, a basic one, one day the orginial hard drive went out so i went and bought a Seagate one, it came with a cd, i installed the new Harddrive, put the Cd in, have it where the cd rom boots before harddrive, cd works i follow instructions and make it where it has xp partitions then it tells me to eject disk and put in OS disk and restart.. So i do and the COMPAQ in red letters come up then a blinking curious like this _ blinks for a min then says "NO OS SYSTEM FOUND ON HARD DRIVE PLEASE INSERT OS CD PRESS ANY KEY TO BOOT FROM CD ROM" (not EXACT wording but close) so i put in xp pro cd and press any key and the same damn message pops up so its like the CD rom i have isnt reading the cd.. however it reads the seagate install just fine. SO therefore i run the wizard again whip the drive re-put xp partitions on.. now im getting this "NTLDR IS MISSING press ctrl alt and del to restart" i have tried a number of things, looked at the guide on this fourm, but i cant get the blue windows xp window to show up sense its not booting from the cd no more. I have had this same problem but i have gotten it to work i just cant remember how. IF someone can refresh my memories that would be great. I got it to work with Windows Home one time in the past but have whipped the drive clean sense sense i was gonan use it just as storage on this computer.. and now im using a Windows PRO cd trying to get windows on it again for my newphew to have a computer.. does it matter im using a diff. version of windows now? i figured sensed i wiped the drive clean it wouldn't matter.. I have also copied all files from this computers hard drive, into the seagate and tried to put that seagate with all the copied files into the broken computer and all i get is a blinking curious like this _ no messages pop up.. So i whipped the hard drive clean again put xp partitions and get the NTLDR is missing message. I don't got a floppy on this computer, i was thinking of burning the boot up files on a cd-rom but i don't see how i can put that in then xp in at the same time unless it asks for disks.. haven't tried it yet.. not sure how all that works. any ideas would be great. PS. I have the jumper set to "cabled enabled" or something like that.. I did have it on MASTER and tried it and same errors.. I have tried every Jumper combo it shows on the front of the HD. If it absolutely matters to have ti on MASTER before whipping then please say so.
