Hello, everyone.
Up until several weeks ago on my Macbook Pro (mid 2012) I could switch with no problems between OS X, Ubuntu and Windows 7 (installed through Boot Camp) using rEFInd. Then I decided to remove the Ubuntu partition and maybe go back to Fedora, and that's when the problems began.
I have to specify that I set up my triple boot system when I had OS X Mavericks. I'm writing this because I noticed that after the upgrade to Yosemite I had a new partition I did not create called "Recovery HD".
After I removed Ubuntu I couldn't boot into Windows anymore, as apparently its bootloader had been overwritten by grub. I googled for a while and somehow managed to remove grub. Obviously this left me with no way to access the Windows partition.
I think I may have made some mistake in removing Linux seeing as in rEFInd it still shows up as a possible boot, but there is no Linux partition on my disk; also, the EFI partition disappeared.
I tried to fix the Boot Camp partition by creating a Windows live usb to access the Recovery tools, but every time I make one I get a "No bootable device found" error. I tried several methods to create a bootable usb (dd via OS X terminal, rufus on another Windows installation on VM, Boot Camp Assistant and unetbootin on OS X), but none really worked.
I also tried basic stuff such as verifying and repairing my volumes on Disk Utility, but got this error:
"This disk doesn't contain an EFI partition. Back up your data and partition the disk"
So earlier I used a gParted live usb to create a 200 MB FAT32 partition (with "boot" and "esp" flags) in the space where the old EFI partition used to be. While I was there I tried to use ntfsfix but got no apparent results.
I went back to Yosemite and tried again to Verify the disk on Disk Utility and this time I got:
"Error: couldn't find the target disk for this operation"
In short, I don't know what to do anymore. It seems one thing led to another and now I can only work on Yosemite. I thought about wiping the entire disk clean but I have no backups and no time to make some; also, I haven't got any backups of the Boot Camp partition. I hope someone here can help.
Thank you.
