Windows 7: XP + Seven: Boot Manager missing on XP

XP + Seven: Boot Manager missing on XP

Hello all,

I use XP on my machine with two 300 GB HDs configured as RAID1 (Nvidia NForce 570 SLI). There are two partitions C (100 GB) for system and D (remaining 200 GB) for data. All is working fine.

Now I try to install Windows 7. First I resized D by 100 GB and installed W7 on this new partition. I updated the Nvidia NForce RAID driver and can see correctly my RAID under W7.
My problem now is that if I start my computer always the old XP boots up.
The Boot Manager is not present. The only way I can boot W7 is to insert the
W7 installation DVD (and not pressing any key) then W7 is booting.
The boot manager is present but only on this new W7 partition. I already tried (using EasyBCD under W7) to add the old XP as a second entry in the Boot Manager but I was not able to boot XP using the boot manager.
I see the XP-Partition under W7 and vice versa but it seems to be impossible to use the boot manager.
How can I install the W7 Boot Manager on my XP-partition, thus I will be able to
choose whether to boot XP or W7.

Thanks in advance for any hints.

Here is my disk management:

Sorry but my language is german.
What you can see as Drive 0 is my old HD (75 GB) used only for temp stuff
Drive 1 is my RAID (298 GB) consisting of Partition "System D" where my XP is installed, you see the partition is active, and this is a primary partition. When I boot XP it apears as partition C. The second one is the partition "Daten F" this is the partition where my data is stored. The third one is this I used for my Windows 7.

The boot menu that you see at startup is defined by the bcd (boot configuration data) in Windows 7. Therefore there should be an entry for both Win 7 partition and XP partition in the bcd as well as an entry for the boot manager. To display the information in the bcd, open an elevated command prompt and type BCDEDIT. If any of the three entries are missing you will not be able to boot to that OS from the boot menu displayed at startup.

The easiest way to add/remove entries in the bcd is throuugh EasyBCD. If you have correctly installed XP and and then Win 7 afterwards they should both show as bootable OS's in EasyBCD.

Also your screenshot is not working. I think Pauly wants to see that you have two bootable OS system partitions on your hard drive. It can not be ascertained from your description.

Win7 is somewhat allergic to RAID. It challenges it's ability to otherwise correctly configure multi-Boots.

We also have a problem troubleshooting RAID installs here because the fixes that otherwise work so well rarely work. Yet we have at least one RAID problem a day.

You can install EasyBCD 2.0 beta which is highly automated, attempt to Add any OS not listed using the Add/Remove tab. If any tool is already acclimated to RAID, then that would be it.

Thank you all for trying to help to solve my problem .
I tried the EasyBCD 2.0 Beta but my XP was not automaticaly recognized even by this version of EasyBCD.
From what I learned here in this forum, a clean Windows 7 Setup, maybe, will be my best option to avoid unwanted surprises in the future. I tried to keep XP for having
a smooth transition from XP to Seven, but in connection with my Nvidia RAID it seems
to be challenging.

See if you can remove the RAID, connect only one HD, then boot from the Win7 installer, select Custom install and use Drive tools to delete all, create new partition(s) as you wish, then format before installing Win7 to the first partition.

LOL.

Very strange drive labelling.

The "system" partition is actually the one you have labelled Drive_C.

The logical drive you are booted into is C.

Try setting Disk 1 as first in the Bios boot order , then run startup repair from the 7 dvd 3 times.

Congrats for being able to interpret it.


What is that Active System D: drive on DISK1? XP?

Will WIn7 Startup Repair put the MBR there to include XP in Dual Boot?

Or does he then need to get Win7 started up, unplug or swap DISK0, run a Repair Install to correctly reconfigure the dual boot with Win7 and XP on only DISK1?
