i accidentally installed another os on my E: (my main is on my C: ). is there a way i can just delete the os on my E:?

tlarkin

just delete the files and edit the boot.ini file to only have c:\ as a boot option (assuming you are running windows). If you are using a boot loader you need to wipe out the mbr and rebuild it.

how do i edit the boot.ini file? and what exact files do i need to delete? sorry i just dont want to make another mistake

tlarkin

give us the full info on your rig's set up. What OSes are installed and how did you install them? I take it you want to make sure there is no data loss? Can the other HD just be wiped and formatted or is there data on there?

there are two xp pro's installed, one on drive C, that has just about all my important data, and one on drive E, that doesn't really have too much data on it. it only has my music downloads, and a couple movies so i guess i could just reformat it. if i transfer that data to my C drive, should i just reformat it? will that fix the boot problem, will i no longer see both copies of xp when i boot?

What OS are you running on the primary? If you are running XP and have a full install disk for it generally that would be the alternate method other then using the disk management tool found in "Control Panel>Administrative Tools>Computer Management". There you double click on the disk management link to open a screen showing the drives detected on the system.

One more or less universal tool for deleting existing partitions on any drive as well as being able to create new ones is the Linux tool known as the Gnome Partition Editor. While XP if that is OS run has it's own disk management tool in the control panel and tools found in the installer when booting up from that I manage to keep a copy or two of the GParted Live for cd lying around for multi OSing drives here.

im running the same os as the primary os too. i acutally installed them both from the same disk. i remember messing with this when i partitioned my hard drive a couple months ago. i dont have that partition software you mentioned, but reformatting should pose a problem. if i right click my ( E: ) in the disk management, it has a button that says "format." should i save what i need and just reformat the E drive? and will this delete everything the last os install actually installed? (including the boot sequence)

If you installed XP twice while both drives were plugged in that will mean your mbr will have had changes depending on which installation went first. If you installed to the second drive after the first you can edit the boot.ini file to remove the single entry made there with notepad. You first have to right click on the boot.ini to uncheck the read only and click apply there and then edit that with notepad and choose the save as under the identical name.

The disk management tool is easy enough by referring to the help section under disk management. The following instructions are found there under the contents directory's help topic to explain the method.

To delete a partition or logical drive
Using the Windows interface

ok quick question in modifying the boot.ini file. which one should i delete? i'm not sure, these are the 2 that come up:

multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Micro soft Windows XP Professional" /noexecute=optin /fastdetect
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Micro soft Windows XP Professional" /noexecute=optin /fastdetect /usepmtimer

and when i delete it, i just save the notepad under the same title right?

That will get rid of it, you still need to rebuild the boot.ini file. You can right click on my computer and go to properties, then click the advanced tab, then click the start up and recovery button, then click the button that says edit booting manually. this will open up the boot.ini file, and by default it should look like this:
Simply delete the lines containing the second install, save and reboot, should fix the problem. If now we can rebuild it from the command line but you have to boot into recovery console.
