Slow reboot after deleting bootcamp partition

Hello,

I was just told by a tech store that my bootcamp partition was slowing down my computer incredibly. I no longer need this partition so I went into Disk Utility, clicked the partition, and deleted it. I also had my RAM updated from 4GB to 8GB. I have an Early 2011 Macbook Pro, operating on Yosemite.

The only question I have is, when I rebooted my computer for the first time after deleting the partition, the restarting process took much longer than normal. Without the bootcamp startup, I figured the startup time would be less, when in reality, it was longer. Is there something I missed while deleting my partition, and is there a way to fix this and speed up the reboot time? If not, will this slow reboot be a one time issue?

Any comments would be appreciated!

Thanks,

Rachel

Mac Pro, OS X Yosemite (10.10.1)

Yes,

You missed the directions to use Boot Camp to remove a Boot Camp partition. You should not have used Disk Utility (it can cause problems)

Open System Preferences and verify that your Mac partition is set as the startup disk.

Then check the available disk space on the Mac partition.

I opened system preferences and the only available option is my Mac side.

When I opened up Disk Utility, this is what my partition looks like. Do I need to drag this box to the biggest it can be and click Apply?

There is a hidden Recovery HD between the OS X and the deleted BC partition, which you can verify using

sudo gpt -vv -r show /dev/disk0

in OSX Terminal.

BCA does a better job by also relocating the Recovery HD appropriately and giving you a contiguous partition.

The only other method is to subsume Recovery HD in OS X partition and then re-install OS X which will rebuild Recovery HD. This does not modify any of you files, but just the OS.

You will also need to clean the Hybrid MBR which is now dangling and inappropriate for your case.

Hi there,

I had exactly the same problem than rkalisher. I tried to remove a Windows partition with Disk Utility and since that, my Mac is booting like 5 time slower than usualy.

I read your answers and re-installed OS X (Yosemite 10.10.4) with the Recovery HD partition, but now it's even worst...

What should I do ? My Disk Utility says that my HD seems ok thaugh...

Also, I don't know how to clean my Hybrid MBR.

Thanks a lot !
