Windows 10 – Upgrading an old laptop

So I took an old laptop I used at university – about 5 or 6 years old but a good model in it’s day, a Dell Latitude E5510 – and decided to use it as a quick ‘test’ run of the Windows 10 upgrade since it hasn’t anything too important and my main PC is being stubborn over actually offering the update.

Unfortunately, it didn’t go so well really. Thought I’d write up a quick post about a 0xC000000F blue screen error that ended up happening.

I’m about to do a particular repair so will see if it works, but I’ve surmised that the issue is that the default Dell partition table looks like this:

– DellUtility (~40 MB)
– RECOVERY (~8 GB) (Marked as boot)
– OS (~130 GB)

What seems to have occurred is that the actual install proceeded reasonably well, I can see the signs of it being completed such as the presence of the “Windows.old” folder etc. However, what Windows 10 decided to do to facilitate the install is that it saw the boot partition and hijacked its boot to use as its boot sequence.

For some unknown reason, in so doing, it increased the “RECOVERY” partition size by 1 sector – encroaching into the “OS” partition and wrecking its MBR and boot sector. This left many tools, including Windows 10, unable to ascertain the structure of the drive as NTFS. Chkdsk understands the corruption but does not resolve the partition table overlap.

I’m going to manually adjust the recovery partition down and try to repair the MBR from its backup. Let’s see how that goes.

Microsoft – partition management: 0 out of 10 for wrecking my MBR!
