home windows – Bootcamp not showing as bootable disk on Excessive Sierra
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 repeatedly 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/Choice – 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 folks 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 might 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:

https://discussions.apple.com/thread/252776981?sortBy=finest&web page=3
I adopted the directions there (utilizing fdisk, not gdisk) and on the face of it, all the pieces appears nice – no less than in my eyes. MacOS is of a distinct opinion sadly, so I’m at a lack of what to do now. I present some primary display screen pictures beneath, which hopefully would possibly present clues.
I do discover now that the gpt command exhibits “Suspicious MBR at sector 0” now – not sure if that really was there earlier at present.
Wanting on the MBR it appears like this
The Bootcamp disk is obtainable in the entire following conditions:
- Disk utility in MacOS
- Finder (exhibiting 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 (won’t boot although)
- Startup Disk (in System Preferences)
So, the fundamental drawback is that it appears to be virtually accurately configured, however not absolutely, and the disk is simply not exhibiting up whereas booting (and urgent Alt/Choice).

In an effort to exhaust all options I did strive 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 a substitute and downloaded a “recent” x64 model (ISO) from Microsoft’s homepage and began making a bootable flash drive (dimension 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 beneath.
I seemed into this concern, 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 changed into 🙂

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 changed into a too advanced a maneuver, particularly since I used to be capable of salvage the information of curiosity (I hope).
Nonetheless, I very a lot respect the help alongside the best way, which gave me some new insights in addition to dragged me to a choice level.
Many thanks!
…and hopefully this put up could also be of utilization to someone else sooner or later.
