dual boot no longer work after windows 7 service pack updated!

[red jersey]

I have two os installed, first I installed windows 7 on my hard drive, then I partitioned a section and install 10.6.3 on this partition.

 

Everything worked fine, so when I booted my pc it sets mac os as 1st boot sequence and if I want to load win 7 I'll have to manually set boot sequence to windows 7.

 

I wanted to update my windows 7 to sp1 and for reason it failed, I googled the solution and one said that to fix this problem go to the disk management, right click my C drive and "mark partition as active".

 

I tried it and it worked, however I no longer can boot my mac os! Everytime when I booted my pc it loads windows 7 immediately.

 

So is there any way I can fix this problem? thanks in advance

 

google is my friend now I'm using my mac os

 

to answer my own question, first boot into windows 7, google easyBCD (it's free) and install it.

 

once installed, open it, and select "add new entry"

then click on mac os tab, select it then add it, save boot settings

 

reboot pc, then it should be fine

I'm not sure how you made your system or is there any problems at all, but here's somethings what i noticed...

 

I have a dual boot system where OSX and Win7 are in their own disks.

 

When you run Win7 service pack, you must have Win7 as "de facto" booting disk, no tricks - it must be the first partition. Only then Service Pack can be installed. This is same as making backup with Windows tools, only when Win7 is primary you can make it.

 

After Service upgrade, you can change OSX back to primary. This is the reason I have to different HDD's.

 

One strange thing; after Service Pack you see "old" Longhorn (Vista) boot logo, so there are some changes in Win7 boot configuration. Normally you use Vista Recovery Tools for fixing boot even in Win7.
