I deleted Mac Os hard drive partition during bootcamp windows 8 installer. Now i can't reinstall Mac Os

I just reinstalled Mac OS (mountain lion) and installed windows 8 via Bootcamp. During the install I accidently deleted the partition where i installed MAC os on.
Now i just can't install Mac OS, i run windows fine. I been searing the web for a solution, but nothing seems to work for me.
I've tried to make a partition in disk manager in windows (once with NTFS, and also in FAT32 format), then i reboot my computer and hold the command key, go into revocery and press reinstall, but I cant choose any of the discs who appears. I tried to delete the diffrent partitions in disk utility in the recovery. But the system just gives me an error, and woun't allow me to delete any of them. I still got my partition with Mac Os Mountain Lion install on (the recovery) on, but how do i get it installed again? I also tried to press the command + r button and do it through the web, but without any luck.
I've tried this topic https://discussions.apple.com/message/17703007#17703007 , but dosent work!
Really hope someone can help me, since i haven't found a topic who solved this for me.

You can't install OSX on a Fat or NTFS formatted partition. OSX needs HFS+.
Boot to recovery, erase your disk, reinstall OSX and then redo Windows.
Read the Boot Camp directions (available on page 1 of Boot Camp Assistant)

I went to Mac Store and had replaced hard drive because I encountered 4HDD ERROR(hard drive failure). I had backed up my old hard drive by TIME MACHINE regularly. Now how can I restore everything I had?

Thanks for your response.
I had tried COMMAND+ALT+R which led me to directly to INTERNET RECOVERY via wifi. After 1 hour or so it dropped me at the same point.
I've tried MIGRANT ASSISTANCE as well, it kept on LOOKING FOR OTHER COMPUTERS even though I clicked on TIME MACHINE BACK UP USING EXTERNAL HARD DRIVE
so what to do now?
P.S. Guys at MacStore were so careless to even listen to me when I asked them about retrieving back up :(

Hi Michele,
Sounds like a corrupted partition map. Can you run the Bootcamp Setup Assistant again to restore the drive to a single volume? Otherwise, I'd backup the OS X side and then re-partition the drive and start from scratch, then restore your backup so at least you'll be back up and operational on the OS X relatively quickly.

I threw out 24 time machine backups from an external hard drive into my desktop trash and now I can't empty my trash.

I threw out 24 time machine backups from an external hard drive into my IMac desktop trash and now I can't empty my trash.

Since you didn't mention what type of error message you were seeing, I'm going to guess on what is happening.
I'm guessing that since you threw away Time Machine backups, that Time Machine is probably active on your Mac. There is a chance then that the files you tossed are marked as in use. You can't delete files that are in use.
Try turning Time Machine off, then restart your Mac. Then try deleting them again.
Once done, turn Time Machine back on.

Deleted QuickTime 10 so I could get QT7 Pro, but now I can't reinstall ANY version of QuickTime.

I purchased & tried installing QuickTime 7 Pro on my MacBook Pro running OS X 10.6.8. I already had QuickTime version 10. The instructions said I needed to download QT7, but it wouldn't install. So I tried deleting QT10 by moving it to the trash & emptying it. WIth that gone, I downloaded & installed QT&, but it wouldn't show up in the Applications folder, even after it said it was successfully installed. I even tried installing it from the DVD that came with my computer. Once I did get it to show up, the icon was different; it was like a notepad & a paint brush or something, but it wouldn't do anything. When I double-clicked on it, it would appear, then instantly disappear. Next, I tried copying a working version from another computer to my MacBook. Now, the QT7 icon is right, but it still won't open. What do I do now? I don't even care about QT Pro now; I can't even WATCH videos on my laptop. The QT7 icon is in my Applications folder & I was able to drag the icon to my dock, but it immediately closes/disappears when I try to open it. Does anyone have any suggestions on how to get QuickTime working again on my computer? Thanks in advance!

You've messed things up by deleting QuickTime X and trying to install the wrong version of QuickTime Player on your Snow Leopard machine.
http://support.apple.com/kb/DL923
QuickTime Player 7.6.6 installs in the Utilities folder and QuickTime X is installed in the HD/Applications folder.
You can run two versions of QuickTime in Snow Leopard and Lion.
Delete the wrong one from the Applications folder and open QuickTime Player 7 from the Utilities (after the download and install) to enter your registration.

PB G4, hard drive partitioned

Hello, My PB G4 has its hard drive partitioned into 4 equal, separate discs. Can I merge 2 or more of these to make a larger disc? Thanks.

Allan,
I "inherited" this partioned disc and computer from my work, from which I've retired, but was allowed to keep. The IT guy who initially set it up partioned it for reasons that elude me. My problem is with iPhoto; I have too may pictures and it has used all the space in the partition. Is it true that the iPhoto app and its picture folder need to be on the same disc? I've been working under this assumption, and this is the reason I need to create a larger disc, by merging 2 or more other discs, to handle the iPhoto picture folder. I ope this makes a bit of sense. Thanks again for your help.

Moving Garageband Music Files to MyBook for Mac External Hard Drive on OSX 10.5.8 I'm a musician and need to make space on my mac hd. Is it safe to move music files there and delete them on the mac? Thanks!

use a MyBook for Mac external hard drive.
I need space on garageband or the entire hard drive, since I am getting the "need space on the hard drive" messages.
It's scary to move my precious music files!
How should I move them to the external and feel safe about doing so?
Or are there other methods besides the obvious, clearing caches, deleting the trash and downloads, etc., that are recommended?
I am doing music now and producers are waiting for the new vocals!
Help!
Thanks!

The process is as simple as just copying your Garageband project to the external drive and deleting from the macs hard drive. But before you delete anything you really need to back them up to someplace else also. Having just one copy is not safe. Get another external drive, DVDs or even flash drives, you absolutely need anything important in more then one place.

Creating Partition in Mac Mini Hard Drive

i Have buy a mac mini a week ago, but before three days ago, some file got corrupted, and it does not start, only the password screen appears, when i entered the password, the screen appears again. and it continues. Now i want to partition the mac mini hard drive. i have only one drive, and i want to create another partition in the hard drive. when i create another partition through the disk utility , i gives error, and cannot create the partition. i acutally want that first i make partition in the hard drive, and after using the "restore from time machine option" to install the mac osx lion in the system. Please help me in make the partition in the hard drive.

Apple themselves don't specify hard drive RPM because they buy a number of different drives, some apparently 4200 some apparently 5400.
It's no surprise that your retailer wants you to buy a G5 though, and is trying to upsell one based on the minis weaknesses - after all, they get more money from a G5 sale than from a mini. They may also be considering your planned use of Photoshop as a stumbling block to effective use of a mini, but the question really is what you intend to use Photoshop to do. If you're a hobbyist, the system is fine and will work more than adequately - particularly if you max out the RAM. If you're a professional user with pro-level expectations, then a mini likely wouldn't be sufficient, not so much due to the drive speed (powerbook users have run Photoshop verisons for years quite happily on what are predominently 4200rpm drives) but because for pro work, Photoshop needs a lot of hard drive space and a great deal of RAM.
On the basis of what you've posted, I'd say your retailer is more interested in their profit than your need. Chances are, if you run PS on the G4 listed in your profile, you're already running on a drive of similar general performance.

My Mac's hard drive is full. Mostly of pics and movies. Can I upload and move photos to Icloud, then delete them from my Mac? If yes how?

Use something such as OmniDiskSweeper (my favorite) or Grand Perspective to find out where large files may be. iCloud isn't going to help much if you've so much data that it won't fit on a 1TB drive. Sounds as if it's time to either buy another drive or at least an external with more space.
Good luck,

My Passport for Mac external Hard drive is not recognized

I recently had to purchase a new MacBook Pro, and when I tried to get files off of my Passport for Mac external hard drive. I get an error stating "The disk you inserted was not readable by this computer." And when I try to initalize, and verify disk, I get this message "Partition map check failed because no slices were found.". I have already updated firmware for the external hard drive. One site I found stated that it could be that the USB port is not strong enough, and I would need a 2.0 Booster cable. Does anyone know if this would work?

What did you old Macbook die from? Likely the HD in it is still ok, yes?
You can remove the HD inside your old dead Mac and put it into a $20 HD enclosure or HD dock, and remove the photos that way, very easy.........IF your old Macbook died from something other than ALSO a bad HD.
You said----my OLD Macbook pro which recently lost video
What happened with your old "dead" macbook? Still have it?

New to MAC, External Hard Drive Problem Transfering files to MAC

Hello All.
First I'm new to the MAC world, just bought my powerbook pro yesterday. Love it. I tired looking for this topic and found similar post but no solutions that I understood.
10.4.9
I have a 260GB NTFS external hard drive with about 100 gigs of info on it. I used it with my PC, running XP Pro.
I want to be able to access that HD from my MAC but all I can do is read, I cannot write. I was hoping it would just hook up to my MAC and I'd be able to read and write.
I do not need to be able to use this HD with my PC anymore. I'm 100% MAC now. I was hoping someone could give me some advice on how to make that happen. Do I have to reformat my HD? What system is that FAT32, NTFS? Something else? And how do I go about doing it?
Thanks to all.

Welcome to Apple Discussions!
You are correct, Macs can only write to FAT32, or Mac formatted hard drives with the built-in software, unless the Mac is networked to the PC, as this article describes:
http://docs.info.apple.com/article.html?artnum=19652
You can also add Macfuse to the Mac, to connect to an NTFS drive, and that's linked here:
http://code.google.com/p/macfuse/
To reformat the drive, you'll have to erase it with Applications -> Utilities -> Disk Utility. Thus before you can reformat it, you'll have to copy over any essential information. The Partition section under Disk Uitlity lets you create a GUID Mac formatted partition under its Options button, and that is ideal for both Intel iMacs and MacBook Pros. If the label under the screen says Powerbook, let us know, and we'll direct you to that forum instead, if we can't answer your question here. Apple Partition Map on the other hand is the ideal for Powerbooks, and PowerPC based Macs. Formatting GUID or Apple Partition map, will let you boot from that drive, to verify that a clone backup was done properly depending on which Mac you made the clone for. Formatting FAT32 or NTFS won't let you make a full backup of your internal hard drive, and only will let you use it for backing up user documents. I highly recommend Shirt-pocket Superduper for backing up, as my FAQ* explains:
http://www.macmaps.com/backup.html
P.S. The MacBook Pro is the Intel version of the Pro notebooks. You posted to the Intel iMac forum. The Intel iMac looks like: . So unless you have that Mac, you are in the wrong forum. There is no such Mac as the Powerbook Pro. You'll see the label in front says MacBook Pro below the screen if that's what you got. Here's the forum for it for category reference:
http://discussions.apple.com/category.jspa?categoryID=190
And pick a forum within it to post a new topic, if I can't answer your question here.
In addition, this nomenclature article will be helpful as well:

How do I replace my internal hard drive and not lose windows partition?

Hello,
I am wanting to swap my internal hard drive out for a larger one. What do I do about my windows partition? I only use boot camp, and there is some stuff on my windows side I don't want to lose. I know how to make a clone for OSX, and I know how to replace the actual hard drive, it's just the windows that I am a little sketchy on.
Thanks for your help.

WinClone - check the faq and forum for tips and read the docs
http://www.twocanoes.com
Pull your hard drive and put it in external case, OWC sells such kits, you could probably use a good windows clone program too.
but you need room on an (external) hard drive to hold the Windows image (uses a sparse disk image file is all).
Paragon Software has been busy releasing programs and updates to help Mac users running Windows, using NTFS (and EXT2/3), as well as CampTune (free for now) for resizing Windows or linux boot camp partitions.

Deleting photos from hard drive

I have been using iphoto since 2009, but I really don't like it. I want to switch to Picasa. I have saved my photos to an external harddrive. Then I unplugged the external. I then moved the iphoto from the dock to the trash. I also removed picasa. I then tried to download Picasa again to basically start over. When I reloaded Picasa, it found photos on the hard drive (my external is unplugged so that's where I assume they are). My problem with Picasa has been that it finds multiple copies of each photo (as I have been using iphoto and then every once in a while I physically drag the albums to an external harddrive.) I have about 20,000 photos so multiple copies make it unusable.
As I said, I have saved my photos to an external hard drive (actually 2 external harddrives because the 80 gigs got filled up!) I want to completely start over with photo editing, and I want all the photos in basically one place.
Can anyone help me figure out how to delete the photos from the imac hard drive?
Thanks,
jules
I really, really don't like the mac at all (and it's been about 3 years!!)

Hey Terence,
I was reading through many of the questions and answers on the site and I saw that you seem to have answered all of them. I tried to figure out how to get directly to you--but I couldn't figure it out....so thank you for your reply. In advance I apologize for explaining everything in minute detail!! (Larry's post was helpful also!!)
I have had iphoto for about 3 years now. I have never been very happy with. If you can "fix" it, that would be great. I am a very organized already with my photos, so that is not the problem. I save all photos into monthly "events". When I back them up, I save them in specific folders for each year with subfolders for each month under each year.
I've been using the Mac for so long, I can't even remember what I used before that, but I remember that I worked with one folder (event) at a time and I had to click into a folder to look at photos I wasn't currently working with. It seems to me that every time I open iphoto, I have access to every single photo I have ever taken at one time. It is VERY slow. Lately, more often than not, I keep getting stuck when I try to open it. I get the colored wheel that lets me know that it's "working". I walk away from the computer and when I come back, it's still rolling. It seems to me that it's getting locked. I usually can't even use the command Q to "end the task". I often have to restart the computer or turn the entire computer off from the back of the monitor.
If you have some ideas on how to fix this, I am more than happy to try them. What I like in picasa is the the ability to add text and graphics to the photos, but for the number of photos that I'd actually do that to, I can just import those photos to picasa.
Thank you for your time,
julie

How to recover pictures I deleted from my hard drive and backed up with TM

Hello all,
2 months ago, using the TM for the first time, I decided to delete all my pictures from my MacBook Pro as they were saved with TM.
Then, when I went to look for them in TM, they were gone as well.
Anyway, I do hope, to recover them all?
and.... how to store them so that they don't take so much space on my MacBook Pro?
Many thanks in anticipation, I feel so useless with this all!

TM does not retain files that have been deleted from the hard drive for more than one week. During the weekly consolidation files removed from the hard drive are then removed from the TM backup.
If you are trying to use TM like a regular backup storage utility, then you've misunderstood how TM works. See the following explanation:
About TM "Backup Drive is Full" Alert
TM only deletes older files if they have been deleted from the source and when TM needs space on the backup drive for a new incremental backup. Data are deleted to make space for a new backup, but if TM is unable to delete enough files to free up space for the new backup, then you will get a disk full error. Normal thinning during a backup occurs during TM's periodic weekly and monthly consolidation backups. Note, that on a Time Capsule the sparsebundle grows in size as needed, but doesn't shrink. Thus, from the user's view of the TC it appears that no space has been freed, although there may be space in the sparsebundle.
Once TM has found it cannot free up enough space for a new backup it reports the disk is full. You can either erase the backup drive and start your backups anew or replace the drive with a larger drive.
