Q: Repairing Boot Camp after creating new partition

Hi,

I've got a similar problem.

I've posted my info on this thread:

Repairing Boot Camp after upgrading to Mavericks: Jarvis

Would greatly appreciate you guys working your magic.

Thanks!

Alan Jarvis

Hi,

So today I was playing cs:go, running bootcamp, when suddenly my mac crashed and rebooted to mavericks... I've tried several things on this thread but I still can't boot on bootcamp... I really need some files I have there and I can't access them -.-' Is there a way to fix this and get bootcamp to work again? Tell me what you need from terminal so I can upload it here.

Btw, when I created the bootcamp partition I created it with 100gb and later I upgraded it to 400gb without reinstalling bootcamp but it as worked fine for more than a month so I'm assuming that is not the problem...

I really need some help with this...

Thanks,

Gabriel

Please start a new thread and post a reference here and the output of the following commands.

1. diskutil list

2. diskutil cs list

3. sudo gpt -vv -r show /dev/disk0 (if bootcamp is on disk0, or choose the appropriate disk, as shown in diskutil list).

4. sudo fdisk /dev/disk0 (if bootcamp is on disk0, or choose the appropriate disk, as shown in diskutil list).

5. sudo dd if=/dev/rdisk0 count=1 2>/dev/null | hexdump -C  (if bootcamp is on disk0, or choose the appropriate disk, as shown in diskutil list).

Thanks for replying so fast here it is Can't boot from bootcamp after sudden crash

Did this way work for you as I'm interested in your results for future needs as this way seems quicker, I have spent a while trying to restore my windows 7 DMG image and making it boot, the above way didn't work for my using terminal commands, but I finally just made windows boot.

Chris - I you happened to be online I would greatly appreciate you help in fixing this same problem.  If the syntax is the same I can go through the process outlined here but I'm guessing you would need to see the output of the sugo reporting to be sure?  Thank you in advance.  Dave

DIsco dave are you trying to make a windows 7 DMG image boot after you restore image to boot camp portion ?

D3... Please post a new thread and post a reference to that thread here. It keeps problems cleanly separated.

Please post the output of

1. diskutil list

2. diskutil cs list

3. sudo gpt -vv -r show /dev/BootcampDiskWithoutSlice (where BootcampDiskWithoutSlice is of the form disk0 and is visible from the output of 1.)

4. sudo fdisk /dev/BootcampDiskWithoutSlice

5. sudo dd if=/dev/rBootcampDisk count=1 2>/dev/null | hexdump -C (where BootcampDisk is of the form disk0s4 and is visible from the output of 1. Please note the 'r' preceding the disk0s4 format).

No bootable device — insert boot disk and press any key

Hallo guys,

First I want to say thanks a lot to Christopher Murphy, because one and a half years ago I was having problems the same like the 1st post on that topic and with the instructions from Christopher I was able to get back my BOOTCAMP with Windows 7. Now I think that the commands from the 1st post changed something that is making my current problem appear. All was working like a charm till few days ago when I was get a decision to update to Mavericks.

Previously I was with Mountain Lion 10.8 and with Windows 7 on Bootcamp. The hardware is iMac Late 2010 27'' with 1Tb SATA HDD.

Few days ago I have deleted the BOOTCAMP partition and resized the disk to only 1 partition (with Bootcamp wizzard). Then I made a boot usb stick with Mavericks and then started the installation of Mavericks from my USB Stick. I have deleted all partitions and created a new one when the installation asked me to choose a partition. So everything was fine and Mavericks is ok and working great. Now the problematic part.

I have created a Bootable USB Stick with Windows 8.1 first. I used some windows program to made it which I was using before and never had a problems on normal Computers (PC, not Apple) to boot and installing that windows from the same USB Flash Stick and the same Windows 8.1 and so on. I started Bootcamp Wizzard on my new Mavericks and than I notice that I have only 2 options there:

1. Download drivers

2. Install windows 7 or later version

I have already the bootcamp software support drivers downloaded before and I have leave only the second tick checked.

I tried to press Continue, but the Wizzard told me that it doesn't recognize a Windows DVD and cannot continue. Asked me to insert a Windows DVD and to continue.

Now it's time to say that my DVD device is not working and I cannot use it.

So I was thinking that the problem is coming from my USB Stick and tried few other programs to make a bootable usb stick with windows. That doesn't help.

I started to read and googling the internet. I tried few options from some guys with a close problems. Reset with Options+CMD+P+R, to format USB Stick fully etc. Then I found that if I install daemon tools and mount a Windows 8.1 ISO the Bootcamp Assistant will continue on the next step and will build the BOOTCAMP partition. I made that and restarted the computer with the USB Stick plugged in. I got a message that there're no system disk and to insert one and to press any key to continue (or something like this). Then I made a hard restart and tried to hold the ALT (Option) key after the startup chime. I got the list of bootable devices, but the usb stick wasn't there Only Mavericks partition and HD Recovery one. Tried few more things with no luck.

Then I found a topic where a few guys explaining how to get the 1st option on Bootcamp Wizzard (Create a Windows 7 or later version install disk). I changed the plist file in Bootcamp Assistant, then signed the app with xcode tools and yahoo, I got that option enabled.

I made again a bootable usb stick with windows 8.1 from ISO with the Bootcamp Assistant 1st option. Then when I restarted the Mac keeping the ALT pressed it was a surprise that the USB stick with windows 8.1 showed up. I started Windows 8.1 setup, entered the serial number and then I selected the BOOTCAMP partition and the Next button wasn't active and error message was written that:

"Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disks."

I tried format, delete partition, create new etc with no luck. Then I tried to recreate the bootcamp partition with Disk Utility, but with ExtFAT format and again no luck. I found another topic on internet where some guys are talking that only Windows 7 can be installed in that way on Mavericks BOOTCAMP. I don't know that this is true or not, but I tried with Windows 8.1, Windows 8.0 and now I'm going to get a Windows 7 from a friend these days, but I don't think that it will work.

Is there someone who can help me out somehow or to tell me some tips or opinions what to do next?

Link to new thread: problem with mbr after partition

Hi,

I'm also having issues with my bootcamp partition after upgrading my mac OS X but my upgrade was to Yosemite.  I have also resized my partition before the upgrade.  I shrank my mac partition and increased the bootcamp partition.  The resize was working until the upgrade.

I've read the thread and tried to implement the fixes involved but it did not seem to work.  Either because I missed a key point or it could be another issue.

I've created a new thread with the command outputs you wanted.

Thank you for your help.
