I’ve a MacBook Professional (Retina, 13"Late 2013, 8GB/251GB) on which I’ve had a Bootcamp partition put in with Windows7 for a number of years (in all probability since early days, i.e. since 2014). Initially the MBP ran Mavericks OS, which I thereafter have constantly up to date to present OS of Excessive Sierra (10.13.6). Booting Home windows has by no means been an issue. Till now. Now it doesn’t present up when booting and urgent Alt/Possibility – solely the Macintosh HDD is seen.
Half a 12 months in the past I did the silly mistake of working down free HDD house to one thing like 10 GB and as individuals would possibly know this isn’t actually appreciated by MacOS. Nonetheless, I used to be capable of get again to dry land after studying a number of discussion board posts. I’m suspecting that this episode may need been the occasion that screwed up my Bootcamp one way or the other.
Initially there was a corrupted MBR desk as different posts have handled, e.g. these:

How one can convert a drive from the GPT format to the hybrid GPT/MBR format when utilizing Excessive Sierra (macOS 10.13.2)
I adopted the directions there (utilizing fdisknot gdisk) and on the face of it, all the pieces seems nice – at the very least in my eyes. MacOS is of a special opinion sadly, so I’m at a lack of what to do now. I present some fundamental display screen pictures under, which hopefully would possibly present clues.
I do discover now that the gpt command reveals "Suspicious MBR at sector 0" now – uncertain if that truly was there earlier right this moment.
Trying on the MBR it seems like this
The Bootcamp disk is obtainable in all the following conditions:
- Disk utility in MacOS
- Finder (displaying all particular person information as properly, and I may even copy information to Mac folders)
- In restoration mode (command+R) as a selection of bootable disk (is not going to boot although)
- Startup Disk (in System Preferences)
So, the essential drawback is that it appears to be nearly appropriately configured, however not totally, and the disk is simply not displaying up whereas booting (and urgent Alt/Possibility).

With a purpose to exhaust all options I did attempt with the Win7 boot drive once more after having reset each SMC and NVRAM, however unresponsive keyboard and monitor pad remained.
I thereafter pursued the Win10 avenue as an alternative and downloaded a "recent" x64 model (ISO) from Microsoft’s homepage and began making a bootable flash drive (measurement 32 GB), utilizing Boot Camp Assistant (BCA), from that ISO. Nonetheless, BCA throws me an error message in the course of the course of some 15-20 minutes in, see under.
I regarded into this situation, which after all others have encountered. I attempted the eject suggestion, however there was not any mountings to eject in my case actually, and the one which popped up in Disk Utility couldn’t be ejected because it was in use for the BCA course of.
Horrible wall of issues this has became 🙂

I used to be capable of copy all information I deemed essential to salvage from the Bootcamp partition, so I took the choice to simply erase/restore the partition and repurpose it as Mac house after that.
Simply as you identified, David Anderson, it became a too advanced a maneuver, particularly since I used to be capable of salvage the information of curiosity (I hope).
However, I very a lot respect the help alongside the way in which, which gave me some new insights in addition to dragged me to a choice level.
Many thanks!
…and hopefully this publish could also be of utilization to anyone else sooner or later.
