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 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/Choice – solely the Macintosh HDD is seen.

Half a 12 months in the past I did the silly mistake of working down free HDD area to one thing like 10 GB and as folks would possibly know this isn’t actually appreciated by MacOS. Nevertheless, I used to be in a position to 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 someway.

Initially there was a corrupted MBR desk as different posts have handled, e.g. these:

The best way to 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 fdisk, not gdisk) and on the face of it, every thing 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 photographs beneath, which hopefully would possibly present clues.

I do discover now that the gpt command exhibits “Suspicious MBR at sector 0” now – uncertain if that really was there earlier right this moment.

Trying on the MBR it appears like this

The Bootcamp disk is out there in the entire following conditions:

1. Disk utility in MacOS
2. Finder (exhibiting all particular person information as properly, and I may even copy information to Mac folders)
3. In restoration mode (command+R) as a alternative of bootable disk (won’t boot although)
4. Startup Disk (in System Preferences)

So, the fundamental drawback is that it appears to be virtually appropriately configured, however not totally, and the disk is simply not exhibiting up whereas booting (and urgent Alt/Choice).
