I am having the same problem. My MBP is fairly new and was lightning quick to load into os x. It booted up almost instantly. After i installed windows 7 on the standard bootcamp version that comes with os x 10.6.6 i noticed it was taking a little longer to load. I thought this was normal at first as usually a dual boot system does take longer.
After removing the windows partition using bootcamp, in a bid to return my MBP back to it's almost instant loading form, it is still taking longer to load into os x now even with no windows/bootcamp partition.
Does anyone have any ideas? So far i have repaired permissions and ran the repair disk feature which found no problems.
Just thought I would share this with you.
Prior to installing Windows 7 on bootcamp my MBP was taking about 25-30s to load to the screen where I put my password in. Once I installed and even when i removed the bootcamp partition it was taking circa 43-45s to load to that same screen.
Last night, I ran an erase format and then performed a full install of os x from the DVD that came with the MBP, flushed the NVRAM and reinstalled all the apps I had on there before (this was easy because i have only had it for 3 weeks) I installed Windows 7.
It is now taking around 28 seconds to load to the same logon screen. It seems when bootcamp creates a partition for Windows, the bootloader or some configuration is created which delays the startup disk being found. Hopefully, someone smart enough will work out exactly what it is.
For now, I will just install Windows using VMWare Fusion.
I had the same problem and looked in activity monitor to see if anything was taking up the cpu. I noticed the mds and the mdworking were using a large portion of my cpu, like from 50% to 113%. This problem was due to spotlight indexing bootcamp, which it didn't know how to do since it was windows. I fixed it by making sure spotlight only indexed my current mac osx partion. I went into my system preferences then to spotlight and clicked on privacy. Under privacy I clicked the add button and added my bootcamp partition as to prevent spotlight from searching inside it. I don't know if this will fix your problem, but it definitely fixed mine.
I had the same issue with my macbook.
After much research I still have no idea how its caused but I fixed the slow boot and extensively slow shutdown issue(2 minutes in some instances). Simply reinstall snow leopard. No data will be lost in this installation but it appears some system files get corrupt with a bootcamp installation and the only way to fix it is to reinstall. Now, with a triple boot of mac, windows 7 sp1, and ubuntu 10.10, I get a startup time of about 30 seconds and a shutdown of 3-5 seconds all while in the macintosh os.
I hope this helps someone!
Same problem here. After starting up Mac OSX (10.6.6) the hard disk would keep spinning and spinning make 'lots' of noise. Apparently some program or file was using my HD very intensively. I couldn't find any explanation. The boot up time was ok, but after booting up programs were slow to open and an average word document took 10 seconds to load. Didn't sound as much but this Mac is only three weeks old and OSX used to be lightning fast.
I tried several things and cleaned up old files, used disk utility and searched for errors. Nothing seemed out of the ordinary. I then decided to reinstall OSX. Before doing that I realized it would be much easier to delete WIndows and any file I needed from the Windows partition I simply copied to the Mac first. Used the Bootcamp Assistant to delete the Windows partition and restarted. Immediately my Mac was back to normal. Did use Disk Utility to repair all permissions which found quite some alterations.
Long story short: it's probably easier to copy files you really need to your Mac partition and reinstall Windows if needed. After I removed Windows all was working perfect again.
Question remains: what was causing the over active HD? The HD was making a sound like you would normally hear when an antivirus or indexing service is scanning your complete disk. I think Spotlight could be the cause of slowing your Mac down (unfortunately I didn't see the Spotlight tips till now).
I have the same problem with my MacBook Pro late 08.
Everything was running fine before I install Windows 7...
When I boot on my Snow Leopard partition, I can see the Windows 7 partition mounted. If I unmount it, my MBP is running quite well, but not as fast as before... So I'm trying to figure out why my system keep running slow when a Windows 7 partition is mounted. I'm tired to unmount my partition everytime I boot on OSX to get better performances.
It's very weird because when I boot on OSX with one app open (like Safari) it's very slow, and I hear my HDD working as **** ! No app other Safari open... it drives me crazy... I think Spotlight or something else is trying to read the data on the Windows 7 partition but I can't do anything to stop this except unmount the partition.
Any idea ?
Exact same thing I had. Maybe you van try to get to OSX 10.6.7 which was recently rolled out and see if the problem persists. If so I would copy all my needed files ti the Mac, remove windows 7 and install again. Some people didn't have any trouble after reinstalling windows 7. It's not a great solution but maybe 10.6.7 quietly solved the bug if apple was aware of it. Apple tends to fix a lot without much saying.
I've had the same issue, with Mac OS 10.6.6. After I upgraded to 10.6.7, I installed Windows 7 and shut down my cpu and after around a day's gap I started it up with my Mac partition. I haven't noticed any slow down on my Mac OS's performance, though I only tried this once with 10.6.7. I suggest upgrading to 10.6.7
I had the same problem. It took me several hours to figure out how to fix it. The trick to fixing the blinking cursor slow boot in Windows 7 is repairing the Master Boot Record.
Here is how to do it:
1. Restart your computer into Windows.
2. While Windows is loading, press the F8 (play/pause) key about every second.
3. Select Recovery Mode and press Enter.
4. Click Repair your computer. (Command Prompt)
5. Select a language, a time, a currency, a keyboard or an input method, and then click Next.
6. Click the operating system that you want to repair, and then click Next.
7. In the System Recovery Options dialog box, click Command Prompt.
Type (these commands are safe)
Code: Bootrec.exe /FixMbr
Code: Bootrec.exe /FixBoot
Code: Bootrec.exe /RebuildBcd
*Press ENTER after each command.*
*Restart your computer.*
