Naming a BootCamp Partition

I just partitioned my hard drive for WIndows and have finished the setup. Now I'm back in OS X and the hard drive image for Windows is named "Untitled." I cannot figure out how to rename the hard drive partition to Windows HD. How can I do this?
Thanks!

Not that I'm a BootCamp User myself, but if you've formatted it as NTFS, rather than FAT32, Mac OSX probably won't be able to read or write to it. You may have to do it in your XP partition.

Invisible bootcamp partition after failed removal

Hi everyone
In the process of removing a Windows partition, I accidentally quit Bootcamp (trying to quit another application). Now, the partition neither shows up in Disk Utility nor anywhere else - of course disk space still taken.
Disk repair didn't do anything... Is there any way around having to reformat the whole drive?
Thanks!

celeron,
Well, you are evidently not seeing the same thing I do when I proceed through the Assistant (I have a Windows partition, and have described what I see as far as I can go without actually touching that partition).
Have you tried removing the partition with Disk Utility? We're not supposed to use Disk Utility's dynamic partitioning capabilities with a Bootcamp partition, but you are having trouble with the correct tool. It's worth a try.
Select your drive in Disk Utility (the drive, not a named volume), then switch to the "Partition" tab. Unlock the padlock, if necessary. In the graphical representation of partitions, select the Windows volume, then click the "-" sign below the graph to remove it. Click "Apply" to give Disk Utility the go-ahead. It will either work, or it won't.

Can't remove my ex bootcamp partition...need help

hey....i installed windows 8.1 through bootcamp, then after few days i tried to remove bootcamp partition through bootcamp assistant, but failed during the process.
Then I used disk utility to remove the partition. It did erased the partition but turned the partition into a grey box, named as free space and with a format of free space.
now i cant do anything with that box, i tried to highlight that box and clicked on the minus button but that also greyed out. After highlighting the grey partition, when i click on the + button, it tends to create another partition named as untitled 2, but when i clicked apply, nothing happened. and i cant see the hard drive model number in top left of disk utility..
i'm posting the screen shots....plz help..!!!

1.I tried to click on it but no respond

Success: moving bootcamp partition to an external drive

Background
Due to the relatively small, non-exchangable SSD on my Mac, I'd limited the bootcamp partition to 50GB when installing Windows. I needed to install new software in Windows, but was running out of space fast and didn't have the necessary space on the Windows side. I don't use Windows that often and for that reason, I wanted to move the Bootcamp partition to an external hard drive, freeing up space for the Mac side on the internal SSD. I'd read many conflicting reports on the web, some claiming they'd done it successfully, while others said it would be impossible, because Windows 7 wouldn't run from an external drive. I had a HDD in a USB 3 enclosure, and first tried to install Windows to this (using various guides on the web). I was very close to success with this USB 3 drive, but Windows would fail during start-up. Most reports claiming to have successfully been able to run Windows 7 from an external drive, had used Thunderbolt drives, so I decided to get myself a Lacie Rugged USB 3/Thunderbolt series Solid State Drive.
Hardware used
MacBook Pro 15" Retina Display (mid 2012), 2,3 GHz Intel Core i7, 8GB RAM, 250GB SSD
Lacie Rugged USB 3/Thunderbolt series, 120GB Solid State Drive
Software used
Mac OS X Mavericks, 10.9.2
Windows 7 Ultimate
Plus several free downloads from the internet, see description below.
Procedure
Step 1: Get the Thunderbolt drive to work under your Bootcamp Windows 7 installation.
This should be simple enough, but proved to be a little tricky. Here’s what I did (assumes you are running Mac OS X before you begin):
1. Make sure your Thunderbolt drive is disconnected before proceeding.
2. Restart your Mac and hold down the option key (alt key on some keyboards) during startup.
3. Choose the Windows drive to start up Windows 7 on your Bootcamp partition.
4. After log in to Windows 7, download the necessary driver software for your Thunderbolt drive (find it at the manufacturer’s homepage of your Thunderbolt drive - in my case lacie.com).
5. If the downloaded driver installer is in a compressed format (like zip for example) be sure to decompress it before running the driver installer.
6. Shut down your computer.
7. Connect your Thunderbolt drive to your computer.
8. Start up in Windows 7 (see items 2 & 3 above) and if it all went well, you should now be able to see your Thunderbolt drive under Start>Computer.
Step 2: Format your Thunderbolt drive in NTFS-format.
Still running Windows 7 with your Thunderbolt drive connected and visible to the system, it is now time to format your external Thunderbolt drive in NTFS-format. There are several ways of doing this. I used the procedure described here at tedhhack.co.uk.
Step 3: Follow the directions at intowindows.com to clean install Windows 7 onto your external Thunderbolt drive.
As described at intowindows.com, this involves downloading Windows Automated Installation Kit (WAIK) and running command line tools. At step 9 in the described process at intowindows.com, at the point where the installer asks if the drive you are installing to is a USB hard disk, the correct input is Y for yes, even if your external drive is a Thunderbolt drive (and obviously not a USB hard disk).
At step 10 in the described process at intowindows.com (Reboot your PC), remember to hold down the option (or alt) key at every restart in the installation process, so as not to start up in Mac OS X. Also, since your machine now has two Windows 7 installations, Windows Boot Manager will appear and ask you to “Choose an operating system to start” and there is a list of two Windows.
I don’t know how to tell which one is on the external drive and which one is on the internal drive at this point, but I started with the top one on the list and this turned out to be the one I wanted (the newly installed one on the external drive). If you pick the wrong one (on the internal drive) at first, simply restart the computer and choose the other one. You know you got the right one when the installation process continues and asks for further input.
After the Windows installation is complete (there will be at least one other restart required - remember to hold down the option (alt) key to start up in Windows, and choose the same Windows on the list in the Windows Boot Manager), you’ll be running a freshly installed, but crippled Windows 7, as you still haven’t installed the specific drivers for your hardware. But don’t worry, that will be fixed in the next step.
Step 4: Clone your Bootcamp partition from your internal drive to the external Thunderbolt drive.
In this step you will copy all the software, drivers, settings and other files from your Bootcamp partition on your internal drive to your external Thunderbolt drive. The easiest way to do that is to clone your Windows partition - and to that end you’ll need to download some free software: AOMEI Backupper Standard 2.0 fits the bill perfectly, as it will let you clone at the same time as resizing the partition to fit your external Thunderbolt drive (I went from a 50GB internal Bootcamp partition to a 120GB external Thunderbolt SSD).
1. Download AOMEI Backupper Standard 2.0 (I used the 17MB download for Windows 7), install it, and run it.
2. In the left column choose “Clone” and in the right column choose “Partition Clone”. By choosing Partition Clone instead of Disk clone, you won’t ruin the newly created (but invisible) boot partition on the external Thunderbolt drive.
3. Press Next and choose your internal Bootcamp partition as the Source Disk.
4. Press Next again and choose your external Thunderbolt drive (your newly installed Windows 7) as the Destination Disk.
5. Press Next again and you’ll get a warning that you will erase the contents of the destination partition and it asks if this is what you really want to do. Press Yes to this question.
6. Next screen is an Operation Summery. Toward the bottom of the Operation Summery screen there are a few interesting options: Edit Size of Partition, Clone Sector by Sector and Align Partition to Optimize for SSD.
7. If your destination partition is larger than your source destination like mine was, press Edit Size of Partition. This will take you to another screen, where you can drag to resize the partition. I dragged this all the way to the right to give Windows 7 the full size of my external Thunderbolt drive.
8. Leave the checkbox Clone Sector by Sector unchecked.
9. If your external Thunderbolt drive is an SSD, put a check in the checkbox entitled Align Partition to Optimize for SSD.
10. Now press the Start Clone button.
11. When the cloning process is done, exit AOMEI Backupper and restart your computer (holding down the option or alt key) to start up in your new clone of your old Windows 7 with all the same software, drivers, settings and files.
Step 5: Enjoy running all your Windows 7 applications from your external Thunderbolt drive!
Step 6: Here is where I need help/advice – can I remove the Bootcamp partition on my internal drive now?
I am reluctant to entirely remove the Bootcamp partition from my internal drive, as I am unsure whether this will disable me from starting up in Windows. I would love to hear from anyone here with insight on the matter.

Step 6: Here is where I need help/advice – can I remove the Bootcamp partition on my internal drive now?
To answer my own question in Step 6 above, no, or at least I haven't found a way yet...
Here's what I've done so far:
Used the Bootcamp Assistant to remove the bootcamp partition on my internal drive.
Booted the system with the option (alt) key pressed down and now there was NO Windows drive to choose.
Therefore I used the Bootcamp Assistant to install Windows back onto my internal drive (including installing Bootcamp drivers in the Windows environment). This time I chose the minimum partition of 20GB for the Windows installation on the internal drive.
Booted into the new Windows on the internal drive and installed the drivers for my Thunderbolt drive.
Restarted with the option (alt) key pressed down, chose the Windows drive, but Windows Boot Manager still didn't pop up to allow me to choose the Windows installation on the external Thunderbolt drive.
Booted from the Windows DVD and chose Repair.
Restarted with the option (alt) key pressed down, chose the Windows drive, and now Windows Boot Manager finally popped up, which allowed me to choose the Windows installation on the external Thunderbolt drive again, phew!
So, I can run Windows 7 from the external Thunderbolt drive, but I have to use 20GB of my internal drive for a Windows installation I'll never use. Not the best solution, but at least I've saved 30GB of space compared to my previous Bootcamp partition - and I now have enough space to install the Windows 7 software I need on the external Thunderbolt drive...

Can I install Windows 8.1 as Bootcamp partition from OSX Mountain Lion using a USB stick?

I have the following:
Bootable USB stick with Windows 8.1 - 64 bit
MacBook Pro with Mountain Lion 10.8.5 - it's probably 3-4 years old.
The Bootcamp partition currently has Windows 7 installed.
I want to know whether I can install Windows 8.1 from a USB stick into a Bootcamp partition. Apple's article on the topic refers to Bootcamp 5.1, but my OSX install has Bootcamp 5.0 - I am assuming 5.1 comes with the Mavericks version. I don't want to upgrade to Mavericks because I am running out of space as it is on the OSX partition.
Thus my question. So can I?

Your laptop has a DVD drive, right? If so you need to burn your ISO to a disc, will not work off USB

Upgrading MacBook Pro Hard Drive - cannot get Bootcamp partition to work

Hello,
The other day, I decided to replace my 320 GB hard drive with a 1 TB hard drive/SSD hybrid. I did a little bit of research about cloning the drive before that, and it seemed pretty straight forward to clone the OS X partition, but I wasn't really sure about cloning my Windows partition. Originally, my 320 GB hard drive had 2 partitions: 220 GB for OS X Mavericks, and 100 GB for Windows 8.1.
I bought the new drive with an external enclosure and plugged it in. The first thing I did was open Disk Utility and partitioned the new hard drive (750 GB HFS+, 250 GB NTFS). I figured I would need to partition it first and clone each partition separately. I used Carbon Copy Cloner to clone the OS X partition, and it worked with no problem (I immediately could restart my computer and boot with the partition on the new drive, while it was still plugged in by USB).
Next, I tried using CCC to clone the Windows partition the same way (I realize now that CCC cannot do this). 7 hours later, the cloning was complete, but there was an error that a couple files couldn't be copied. I tried copying them manually but it didn't work. I wasn't sure if the Windows partition would work, so to find out, I switched the hard drives and put the old 320 GB one in the external enclosure. I booted my computer and it booted the new OS X partition with no problem. It also mounted the Windows partition that I cloned with CCC, and I can access all of the files in it. However, when I restarted and held down "option", it would not let me boot the Windows partition.
After some googling, I realized CCC is not able to clone a bootcamp partition and make it bootable, so I opened disk utility and deleted the Windows partition (using the minus button), then recreated it (using the plus button). I downloaded Winclone (paid $30), which supposedly can clone a bootcamp partition. I opened Winclone and it seemed pretty simple: you just choose the source partition on the left, and the target on the right. I plugged in the USB enclosure with my old hard drive, and in the Winclone menu the original Windows partition popped up. I chose that as my source, and chose to copy it to the new NTFS partition on the new drive that I created. I left it on overnight, and when I woke up it said it was completed.
I now had two drives mounted: my NTFS partition that I created, and a new one that said "EFI". I have no idea what EFI is. My NTFS partition looks like it has all of the files from my original Windows partition on it; however, when I restart it does not allow me to boot with it, although I now have the option to boot EFI. When I select EFI, I am given the Windows 8.1 start up screen (with the blue Windows logo), but then an error message pops up saying something like there is an issue and it needs to restart (it restarted before I could read the whole thing).
When I boot in OS X, I only have the NTFS partition (with all my Windows files) mounted, and no EFI. When I restart, I can still boot EFI, but I always get the same message and then it restarts.
Is there any way I can fix my Windows partition so that it works the same way it did on my old drive? What is EFI? Can I delete it? How can I make the NTFS partition, which seems to have all of my files, bootable? I only want 2 partitions: one for OS X, and one for Windows. Also, can I do all of this without having to reinstall either of the operating systems?
Thanks

Hmm, that's a good question!
I headed over to the twocanoes website (the folks that make Winclone) and their guide mentions something about running Sysprep before you create the Windows image. If you skipped that step, that may be why you're having issues
http://www.twocanoes.com/support/winclone/migrating-a-bootcamp-partition-with-wi nclone/
Step 24 in that guide also mentions copying a Boot file - were you able to/did you do that?
You may have better luck over in the Bootcamp forum, which is here.

I have a Bootcamp partition on my Imac with Mavericks which I can't delete because the Partition Layout is greyed out and is stuck on 'Current'. What can I do?

I have a Bootcamp partition on my Imac with Mavericks which I can't delete because the Partition Layout in Disk Utility is greyed out and is stuck on 'Current'. What can I do? I was trying to install Windows 8.1 but apparently, this is not yet possible.
I was originally able to restore to my original Mac OSX partition using Boot Camp Assistant but then after entering Disk Utility and re-RAIDing the default RAID 1 to RAID 0 in the BootCamp partition (I suspect this is the cause of the problem but why was it defaulted to RAID 1 in the first place?!!!!), forever afterwards, I couldn't restore the single OSX partition.
Whenever I used BootCamp Assistant my choice to 'Install or remove Windows 7 or later version' was greyed out. Finally I went to Disk Utility to repartition but the Macintosh HD and BootCamp disk partition functions were also greyed out (even if I started up from Recovery mode holding down option, command and 'R' and choosing Disk Utility). BootCamp Assistant gives the error message 'The startup disk cannot be partitioned or restored to a single partition' with additional small script 'The startup disk must be formatted as a single Mac OS Extended (Journaled) volume or already partitioned by Boot Camp Assistant for installing Windows', and DU gives the error message 'The full size of the Fusion drive is not available for repartitioning'.
What can I do to fix this problem? How can I make the Partition Layout button active in DU so I can change the partition to all OSX? I'm prepared to wipe off all my data etc to repartition and have backed up all to disk using Time Machine.

My problem is fixed now, thank you. It was caused by my changing the Boot Camp partition's 'RAID1' to 'RAID0'. If I hadn't done that, Boot Camp would still have been able to 'restore' back to the one partition. It was fixed with the help of Applecare by using a terminal and typing a command to erase the IP of the Macintosh disk (not the volume) as well as the IP of the Bootcamp partition (if I remember correctly), but then I had to restore the OS and all my applications and data etc which I had previously backed up using Time Machine. I haven't taken note of the exact command terminology used. It would be wise to speak to Applecare about this if possible.
Two words of warning, 1. According to the cause of this problem, it might be wise, after reinstalling the ops system to reinstall all extra applications one by one, manually, in case a similar problem arises again. Then manually copy back all data. Or the Mac user could use the Time Machine backup and then uninstall all the added apps then re-install them one by one manually. 2. Beware as after all this the user might not have the 'Recovery partition'. There is a small recovery partition (a few 100 Mb is size) which comes with all later Macs. After all this is done this tiny partition might not be there anymore and the user might have to re-install Mavericks again to get it back, or just install the upcoming update of Mavericks due in a month or so.

How can I restore Windows 7 to Bootcamp partition - not reformat the entire hard drive?

Hello Apple (Mac) Community,
I originally posted this question over on answers.microsoft, but no help was forthcoming. Hope someone can help me with a problem that's (almost) making me nuts! I teach graphics to college students. In brief: I run Windows 7 Pro 64 on a Mac Pro tower, along with Snow Leopard (OSX). Windows is loaded on one partition of a 1TB drive. The other partition is a Mac backup. The Mac OS is on a different drive. Everything was going swimmingly with both OS, until recently. Unfortunately, the drive with Windows showed problems and I determined that the HD was either toast or needed a total reformat. My Mac data was all backed-up. Now I wanted to backup Windows so I can easily get back to the relatively happy point of my Windows 7 experience (drivers loaded, dual monitors all working, etc.). I did some online searching and the recommendation was to create a "system image" of the existing Windows 7 install by attaching an external drive, formatting that to NTFS and selecting "backup to image" in Windows. I did that and also took the opportunity to "create a backup disc" on a DVD. (Windows recommended). Next I rebooted back to Mac OS and completely reformatted the problem 1TB disc to a single partition, zero all data, just to see if it would actually reformat. It all worked! So far, so good. Next I used Bootcamp to create two partitions, one for Windows. I then restarted using the Win7 Pro (64) install disc, reformatted the Bootcamp disk to NTFS (as required) and installed Windows 7. After all that is completed and all working, I next try to use the restore from image function while booted in Windows. I'm instructed to restart from the Win install disc, which I do. Here's where things get difficult. When I try to choose restore from image, at that point the installer asks which drives to I want to exclude... but does not show partitions, only full HDs. I do not want to reformat the entire 1TB drive. I only want Windows on the 120gb Bootcamp partition (which is already formatted for Windows BTW). I spent a lot of time online reading through articles with users having the same frustration.
So here (at long last) is my question: How can I either restore Windows just to a Bootcamp partition... using "Windows System Image" or if that can't be done... can I somehow import all of the settings, etc. from the "image" (image is on external HD) into a fresh Win 7 install? So far the "backup disc" also seems useless. I can't even boot to Windows from it. BTW Apple folks: the only response on the MS side was that some "expert" simply posted links on how to install Windows and restore... not helpful with my particular problem of restoring to a partition.
Any help would be appreciated! Hopefully some help that even a Mac user / new Windows user could understand would be better! Thanks!

WinClone 3 is OS X and saves Windows image it makes for restore - that should work but you will have to try and you would need to make a new image unless it also works with a native Windows system restore image. It is now supported and has come a long way.
http://www.twocanoes.com/
Paragon Clone OS works and does disk-to-disk clone just like CCC you end up with two bootable drives. But does not work with your setup. It would let you clone and move your Windows install to an SSD or another disk drive though and be bootable.
During its clone process it checks for errors which is very helpful and lets you know - something CCC and others should adopt more of.

Upgrading MacBook Pro 13" (mid-2010) HDD with Bootcamp Partition

I'm upgrading my macbook pro's hdd from 250 gb to 1tb. My OS is lion 10.7.5 and i also have windows 7 installed on my bootcamp partition.
The following are the details to the HDD i plan to buy.
Samsung Spinpoint M8 1 TB Laptop Internal Hard Drive (ST1000LM024) -
2.5 inch Form Factor
SATA 3.0 Gbps Interface
1 TB HDD
5400 RPM Spin Speed
I need your advice on if i m buying the correct hard disk. If not please advice me one.
And please also tell me how i should upgrade my hard disk. I know how to physically install the drive but i ask of you to tell me how to clone my current hard disk with my bootcamp partition. Which software to use, precautions to take etc.
MacBookPro 13" (Mid-2010)
Processor 2.4 GHz Intel Core 2 Duo
Memory 8 GB 1067 MHz DDR3
Graphics NVIDIA GeForce 320M 256 MB
Software Mac OS X Lion 10.7.5 (11G63) and Windows 7 Ultimate on bootcamp

Those are the correct RAM modules for you model (the 13" being the only mid-2010 model that can use 16GB of RAM - but those modules will surely get you to 8GB!).
Am I right in assuming that you want to purchase a SSD to be installed in your boot bay and that you want to install the Samsung drive in the optical bay? Unfortunately, your link points to a rather sparse description of the drive - I see the 2.5" but I don't see the depth (which should be 7-9.5mm and not a mm more).
I'm just unclear about whether you're looking for a new spinning drive as well as a SSD and whether or not the drive will fit (just a minute - OK, found some more info - the Samsung drive is 9.5mm so it should sit just fine in your machine: do you still want a SSD?).
Note that the 2TB Samsung probably won't speed things up much - it's a 5400rpm drive: if you could use a 1TB drive, you could get a faster, 7200rpm drive.

VMware Fusion Performance: Bootcamp Partition or Virtual Machine?

I'd like to run ArcGIS 9.3 in Windows XP using VMware Fusion. Can anyone comment on the virtues/drawbacks of using a bootcamp partition versus creating a VMware "Virtual Machine"?
With bootcamp partition I can gradually increase the size of the partition as the partition becomes full using Drive Genius, correct?
What about performance?
Thanks!

Visit MacTech.com and read their two benchmark reviews of Parallels, VM Fusion, and Boot Camp.
You cannot "gradually increase the size" of a Boot Camp partition. To change the size you must first delete the existing partition then create a new, larger partition. Doing so will delete the entire Windows system, so be sure to back it up beforehand.

Recovering bootcamp partition - is there a solution that works?

Dealing with bootcamp issues after a Lion upgrade seems to be a common problem with no agreed solution.
When I upgraded my iMac to Lion, the upgrade process couldn't create a recovery partition so Apple support advised me to use Disk Utility to create a small (5 GB) block of free space on my harddisk for the recovery partition to use and then to use Disk Utility to enlarge the OSX partition again to recover whatever remaining free space was left after the Lion upgrade had completed.
This I duly did. However, after I enlarged the OSX partition using Disk Utility to recover the free space I found that a) the Bootcamp partition had been renamed "disk0s4" and b) when holding down the Option key when booting, the Recovery option was now labelled "EFI Boot" and appeared to boot from the regular OSX partition. Attempting to boot windows in Bootcamp results in a "missing operating system" error message.
I'm not so worried about the recovery partition as I have a bootable DVD and USB flash drive.
What I would like to do is recover some files from the Windows partition. There is a lot of opinions in the Apple suport forums about what works such as, booting Windows from the install disk and running the "fixmbr" and "fixboot" commands or using rEFIt or BootPicker (which doesn't seem to work on Lion).
Is there a reliable approach to fixing this problem so that I can at least read the contents of the partition, even if I can't boot from it? If I can't actualy recover the partition I'm not too fussed, so long as I can get the data off it.
Thanks...Macs

Why do you suggest installing Lion on an external h/disk? Is this because of problems with Lion or just suggested standard procedure?
Some of the options may work although I am unable to mount the partition at all (in OSX or by booting from a Linux live CD and trying to mount it from there) so I'm not sure how far any of them will get.
I haven't tried booting from the Windows DVD as yet.
If I run Verify on Disk Utility I get this:

From looking at the Fdisk and GDisk output I cannot see where the problem is occurring (although I know 2/5ths of stuff all about partition tables). I notice that the Bootcamp partition is now lacking a name although I don't know whether this matters or not and strangely FDisk identifies it as an HPFS filesystem whereas Disk Utility identifies it as MSDOS (FAT).

Bootcamp partition shows up as grey "disk0s4" in Disk Utility

Hello everyone,
So I am a few days into this tiring and discouraging process of trying to get my iMac back to it's original working state. Here's to hoping for a solution:
Ever since I bought my iMac, I've been running OSX Mountain Lion with Win7 installed through BootCamp, without any problems. I recently wanted to increase my Boot Camp partition size from 80GB to 149GB because I was running low on disk space, and that was the start of many problems to come.
Here's what I tried first:
Make a backup copy of my OSX partition through Disk Utility's "Restore" tab (onto external HD 1)
Make a backup copy of my Windows partition through "Create a system image" in Windows Control Panel (onto external HD 2)
Use WinClone to backup a copy of my Windows partition
Erase Boot Camp partition in Disk Utility
Resize Mac OS partition to max
Create new FAT partition (149 GB)
Restore WinClone backup to the FAT partition (hoping it'll "fill up" the remaining free space)
I don't remember all the details, but all of this led to Windows not being able to boot properly, and then soon after, OS X wouldn't work either. The built-in Recovery HD somehow became unusable and showed up as grey in Disk Utility (too chaotic to remember how). After much trial and error, I was left with the Mac's built in Internet Recovery option, which I used to reinstall OS X Mountain Lion (on top of the existing Mac partition). Afterward, I regained the Recovery HD, and resized the Mac OS X partition to cover over the unusable free space that remained.
After that:
Ran Boot Camp Assistant to start the Windows installation process from scratch.
After the installation finished, I used "System Image Recovery" from a bootable Windows Recovery USB that I created.
Upon restart, Windows would not boot (which was fixed using the bootrec commands within Command Prompt off the USB).
This allowed Windows to boot fine, and it was exactly as it was before this all began.
Now, here are my current problems.
I believe the simplest way to achieve my original goal of extending my Windows partition would be to use Paragon's Camptune X, but upon running it, it tells me it can't find any Bootcamp configuration on my system.
While both OSX and Windows appear on the Startup Manager when I hold down the "option" key (which boot and run just fine), the "BOOTCAMP" partition that I would normally see in Disk Utility (under Macintosh HD) is now listed as "disk0s4", is grey, and "unmounted". It's also listed as MS-DOS (FAT), while it shows up as NTFS within Windows.
The Startup Disk preference pane lists Macintosh HD as the only choice.
I'm exhausted from the past week of repeated backup/reinstallations and trying to make this work. I've done my share of research and reading related forum threads, with no real solution. I am hoping "The hatter" will see this, as he's offered much info/advice on this topic on these boards, but I still haven't been able to resolve this issue.
Thanks for reading, anyone have any ideas?

By using Disk Utility to try to resize your Bootcamp partition you messed up your hard disk. You need to backup all your data from the disk, eraze and format your disk, and reinstall OSx, then if you want a new Bootcamp partition run Bootcamp Assistant.
Next time you want to resize the Bootcamp partition use CampTune, not Disk Utility.

Bootcamp partition is no longer visible and bootable

I decided to change size of my bootcamp (windows partition) by following steps in this thread:
how to resize my bootcamp partition without deleting itit
I ended up with having bigger windows partition (which is what I was trying to achieve), that I was able to boot to, but my Windows disk was no longer seen in OS X. I reviewed the thread above once again and it was pointing to another thread where folks were discussing issue similar to mine:
Repairing Boot Camp after creating new partition
Bottom line - Unfortunately, after performing the suggested action plan, I am no longer able to boot to my windows partition nor to see it from OS X
(I am able to select Windows disk while hitting Alt/Option during the boot, but then I get the message 'A Disk Read Error Occured. Press CTRL+ALT+DEL to restart')
Please see the diagnostics below and please advise how this could be fixed - at minimum I would like to boot to Windows partition again, maximum - also to access it via OSX as well.

So do you think there are there any chances of fixing it?
Though it is sad that resizing of bootcamp is not supported natively (by Disk Utility?) as it seems a lot of people would like to have this.

Windows XP won't install on a Bootcamp partition Following replacement program of 1TB Seagate Hard Drive

Following 1TB Seagate hard drive replacement on a late 2009 machine running Mac OS X 10.6.8, bootcamp would not install windows XP on a disk partition. Now that this is upgraded from OS X 10.6.8 to Mavericks, is it possible to install windows XP on a bootcamp partition?

Make sure your "Function Key" lock is on. Mine did the same thing. I Have a new Microsoft multimedia keyboard and F8 would not work until I hit the "Function Key" lock on the keyboard.
Good Luck

Windows 7 64bit would not install on bootcamp partition

I have a Windows 7 64bit ISO. I inserted a 8GB usb stick into my New Retina MacBook Pro and ran the Boot Camp to install Windows 7 bootable from the USB stick. It all went fine, booted into Windows install, and when I had to select a partition, I selected the only one that said BOOTCAMP and was 40GB, just as I created it earlier when creating a partition size compared to the total disk. I selected the partition and as I could not select next, I selected to format the 40GB Bootcamp partition. It didnt take long, but afterwards, when I clicked next, it showed up an error about not being able to use the partition or something, I cant fully remember.
But now my OSX will not boot. When I turn off the computer by holding down the power button, it turns off, and then when I hold down the power button to turn it back on it does the grey screen part, and then shows a black screen and shows:
No bootable device -- insert boot disk and press any key
What do I do here?

Hold the option/alt key down on a wired or built in keyboard and boot the machine, you enter Startup Manager and thus can get into OS X.
Next, when your installing Windows, you first have to format the internal Bootcamp partition from the FAT32(MSDOS Apple calls it) to NTFS while booted from the Windows 7 install disk, THEN you can install Windows and it takes a lot longer than a few seconds.
Read the BootCamp manual, there is also drivers you have to install into Windows
