Windows 7: Help! I've screwed up my XP partition

Help! I've screwed up my XP partition

Hey there!
I tried to set up a dualboot of 7 and XP, so I made a new partition from XP (named S: ) and installed 7 there.
It finished installing all right and booted to 7, but when I restarted no boot manager appeared and I could only run XP.
So I decided to follow the steps from Method 2 here
Dual Boot Installation with Windows 7 and XP
but I must have screwed something up very badly 'cause I can only access 7 now.
I went into the disk management tool and things have gone weird there: S: drive is now labeled C: (and I can't change it), and my XP drive (that was C: ) is now a logical drive (wtf?) labeled E:
Any suggestions on how to fix this?
Thanks in advance

What happens when you try to boot into XP?

7 is going to see its system drive as C.

How many partitions and HDD's are there and how are they configured?
Can you use the Win7 snipping tool to make a screen shot of your Disk Management?

If you have XP in the first partition and install Win7 second to the same or another HDD on a primary NTFS formatted partition, it should configure the boot properly.

It may be as simple as marking the XP drive Active rewriting the boot sector to the XP partition if it is first on the HDD. But we need more info.

Definitely need a screenshot of Disk Management window, as Greg says:

My apologies for the delay

"What happens when you try to boot into XP?"
I can't boot into XP, I get no OS selection screen, so I can only boot to 7.
I noticed something funny, by the way - 7 will only boot if I have the DVD on the drive, otherwise it shows a message that it was unable to boot and requires the DVD for repairs.
I don't have to access the DVD, but it needs to be there. Go figure...

"How many partitions and HDD's are there and how are they configured?

Definitely... See the attached file

Drive 1: 320 GB
E: (was C: in XP), 120 GB: system drive for XP
C: (was S: ), 30 GB: I installed 7 there
F: and D: (were G: and D: ), that's only data

Drive 2: 320 GB, got a single partition (I: ) with only data as well

"If you have XP in the first partition and install Win7 second to the same or another HDD on a primary NTFS formatted partition, it should configure the boot properly."
Yah, that's how it should be in theory, but something went very wrong

BTW I don't mind having to reinstall or format the partition with 7, I got nothing there, but I do want to save my XP install

Thanks for replying

It looks like your Xp OS was installed on a logical drive. Your W7 was installed on a primary partition which you have correctly created. Had the Xp been installed also on a primary parition, you would get the boot manager showing both OS and whichever OS you selected, the C: drive will then be your boot parition

Here is mine.

You can probably fix this fairly easily using EasyBCD.

XP doesn't need to be on a primary partition as long as the boot manager is on the active partition. The Windows 7 boot manager will call NTLDR which can load XP from a logical partition.

In my case, I have boot, bootmgr, ntldr, ntdetect.com, and boot.ini all on the same active partition. I have XP32 on a primary partition and XP64 on a logical partition and am able to boot into either of them.

Well, I'm sure I had XP in a primary partition before... anyway, as long as I can boot it, I could hardly care less about that.
I have no idea how to use EasyBCD

Download EasyBCD and see what OS Entries it lists when it opens.

Normally you would go to Add/Remove Entries tab and add the missing OS by name and letter, which will then rewrite the boot accordingly.

However, involving a logical parition does make it iffy, so you can try the normal procedure, and/or report back with screenshot of the EasyBCD OS entries to troubleshoot further.
