I have Boot Camp installed on my iMac OS 10.6.8 and have been using it successfully for several years to access a Microsoft accounting program. After a lapse of a few months I find that I cannot open Boot Camp.
I startup the iMac in the usual way while pressing the alt/option key but instead of two icons to start either iMac or Boot Camp, I see only the iMac option.
Any suggestions?
iMac, Mac OS X (10.6.8)
Do you see a Bootcamp option in System Preferences -> Startup Disk?
Thanks for the suggestion but unfortunately there is no Bootcamp option in System Preferences - >Startup Disk
What I do see is an icon labelled Mac OS X 10.6.8 on Mac HD, and a second icon with a question mark entitled Network Startup.
Can you post the output of following OS X Terminal command?
diskutil list
I'll get back to you when I've figured out how to do that.
Go To Applications -> Utilities -> Terminal and launch it. Type diskutil list in the Terminal and press return. Copy and Paste the output as a Reply. Remove any personal information as you see fit.
I think this is what you were asking for.

I do not see a Windows installation on /dev/disk0. Is the 1TB disk an external disk?
All I have is a 1TB internal hard drive, no external drive.
Bootcamp was originally installed on a, I think 5 Gig, partition on the internal drive. It had been working well for the last 5 years.
1. What is /dev/disk1 which is 1TB? Can you disconnect it?
2. You have a /dev/disk0 which is 2TB. Is this an external disk?
3. Do you two hard drives in your iMac?
4. Can you post the output of the following terminal commands?
diskutil info disk0
diskutil info disk1
I was mistaken in my last message, my internal hard drive has a 2TB capacity, not 1TB.
Actually I do have a second 1 TB drive, but had forgotten since it is dedicated to Time Machine backups.
Sorry about the confusion.

Disk1 is a USB-connected disk. You should disconnect it till we can find your Windows installation.
There is a disk scanning software that I use called Testdisk which we can use to scan your 2TB internal disk and try to locate your Windows partition. http://www.cgsecurity.org/wiki/TestDisk_Step_By_Step . The starting UI looks like http://imgur.com/a/PjmnK .
I suggest we try this tool.
Sorry for the slow response but I have been tied up with another pressing issue.
I see that the second link you sent should allow me to scan and analyze my internal drive for missing partitions etc, and presumably facilitate any necessary repair.
I assume that the first link is intended to describe the procedure to do this, but given that I am in totally uncharted territory it is still not immediately clear to me quite how I do this.
In the happy event of a successful outcome, can I expect that the to original contents of the Bootcamp partition will still be intact?
As an example of recoverability, please see Windows 7 Vanished after Yosemite update... help?.
