Why is my MacBook slow to boot?

A couple of months ago my MacBook really started to slow down when booting up. I have a 500Gb HD partitioned 300Gb Mac 10.6 and 200Gb Windows XP. Both have plenty of free space. Now it takes 4-5min for the OS 10.6 to fully boot and the XP won't boot at all, just restarts. Is this a hard drive issue? I might add the HD seems noisier than usual.

I believe you answered your own question. Sounds like your HD has too many bad blocks, bad directory, or is simply on it's last leg. I would clone your XP partition with WinClone and use time machine to back up your OSX User files. Then I would erase the drive with the "Zero-Out" Option in order for Disk Utility to re-allocate any bad blocks on the drive and try to repartition and install both OS'es. If you continue to have issues; then replace the drive.

Another thing you can try first....Run Disk Utility Verification and Repair to see if it helps first. Then try the above recommendation.

+ I agreed, get your data backed up ASAP, before you do anything else, you may only get one shot at it. Then do as Majesty suggests.

Also check to see if your drive is very full. OSX needs space on the HD to swap from. A slow system offen is caused by not enough space to swap and/or heavily fraged.

Besides the HDD issues, there are a few couple of things you can check such as:

- if your Mac is running too many apps at one time.

- if there are lots of Login items.

- if your HDD is cluttered.

- if your RAM is not enough.

- and similar reasons.

With the passage of time, when we install, delete, modify applications and data on Mac, all these activities raises the chances of fragmentation. I think you should Defrag Mac drive with the product of stellar. It helps to keep all fragmented data together in memory and increase the speed of Mac.

I also have the same problem , I fact I thought that spotlight v100 was a virus which I saw on net so I used the sudo rm -r directory name to delete that in terminal. Now my Mac is continously booting since last one night and when I repeated it it is booting since morning and now it is afternoon here .

Rebooting is not the same as being slow. I would recommend you use your original install CD/DVD or external HD/SSD to boot your system and then rename your system folder and then reinstall a fresh copy onto your HD.
