How to run Boot Camp on External Hard Drive?

Thx, meanwhile I finished all installations, and everything looks hunky dory - however, when I tried to use the Windows Backup Utility to create a system image from my C-Drive (LILY) it told me that it would create a BackUp from LILY AND BOOTCAMP, and there was no way to change this. Then after "next" the system issued error "failed backup because one of the disks is not properly formatted - reformat as FAT or NTFS". Obviously I did not do this, but the whole point of the exercise was to be able to have an image of LILY so that after a catastrophic failure I could restore the system from within Windows, rather than taking days and days to reinstall Windows and all applications and the file backup from the Personal Cloud!!! Any idea whether this is at all possible? Best, Steve

Can you post the output of following OS X Terminal commands?

Here you go, thx

1. Can you disconnect disk[4,5,6,7]? Just have the internal 1.1TB Fusion drive and LILY connected.

2. Please try a Windows backup.

I am traveling right now with traditional laptop only. So I'll try out next week. Thx Steve

Hi, I am back and disconnected all non-essential external drives, but I had to retain (NTFS-formatted external hardrive) E: WINAIRBAK, which is my backup destination. Again, Windows did not give me an option to back up C: LILY alone but only together with Bootcamp, and then the backup failed, because obviously Bootcamp is not Windows-formatted.

The output again is:

Would you be willing to try converting the BOOTCAMP FAT32 to NTFS and test? Please backup both OS X and Windows and save files, before trying it. Windows Backup will not support FAT32. The Bootcamp volume is not the boot volume as shown in the Disk Management screen.

I am not sure that I want to to this, specifically because I only have a file backup but not a system backup of C:LILY. I did not chose the FAT32 format for Bootcamp, rather that's what the Bootcamp installer did. If I reformat Bootcamp I'll likely loose all of the drivers, and at the "best" what may happen, that Windows will boot, but then there's no way to input anything, as happened to me during the last crash. If I loose Lily, I have to go through 3+ days reinstallation again. Perhaps I should back-up LILY using Winclone or Carbon Copy Cloner? But that's risky, too. Perhaps I just leave it a what it is for now.

Does anyone know anything about this situation?

I have a second boot external drive for my imac. I'm running Yosemite on the internal drive, but I have mavericks boot drive on an external so I can boot up in mavericks for troubleshooting. I was wondering if I could treat it like the internal drive with a divided partition and bootcamp running windows on it, or will it fail to boot windows because of it being an external drive?

This will NOT work! The Bootcamp installer with your Mav on the external drive will tell you that it cannot because the drive is "not journaled"! I have not found a way around this.

thanks
