Hi all,

I had Windows 8 installed via Bootcamp on Mavericks.

It worked fine after updating to mavericks, and suddenly one day for no apparent reason, I booted and it said no drive found or something.

I read some threads on how to fix similar problems. One particular one said to run

sudo fdsisk -e /dev/rdisk0

followed by

setpid 4

followed by

07

followed by

flag 4

followed by

write

I did this. Here is the current way it looks now:

Code:
fdisk: 1> print
Disk: /dev/rdisk0	geometry: 121601/255/63 [1953525168 sectors]
Offset: 0	Signature: 0xAA55
         Starting       Ending
 #: id  cyl  hd sec -  cyl  hd sec [     start -       size]
------------------------------------------------------------------------
 1: EE 1023 254  63 - 1023 254  63 [         1 - 1953525167] <Unknown ID>
 2: 00    0   0   0 -    0   0   0 [         0 -          0] unused
 3: 00    0   0   0 -    0   0   0 [         0 -          0] unused
*4: 07    0   0   0 -    0   0   0 [         0 -          0] HPFS/QNX/AUX

Now when I reboot, its just a blinking _ cursor with no output.

Is this still wrong? What should I set it to?

I dont have any crazy use cases like multiple boot OS's or anything. I have OSX 10.9, iMac Late 2012. And windows 8 installed on my bootcamp, that's it.

Thanks!

I got impatient and deleted everything and reinstalled w7/w8 upgrade this is what the MBR looks like now. Working fine now.
