**Subject: Windows 11 upgrade is a NIGHTMARE**

So my old gaming rig (i7-6700k, GTX 1060) should *technically* meet the Win 11 requirements, right? Nope. Every time I run the PC Health Check, it fails on "TPM 2.0." I went into the BIOS and enabled fTPM after like an hour of digging.

Now the installer gives me a new error: "This PC doesn't support Secure Boot." Seriously?? I enabled that too, but now it says my drive partition is wrong (MBR vs GPT). I'm about to throw this whole computer out the window. All this just for a slightly newer start menu? Ugh.

Anyone have a magic fix or should I just give up?

Hey there, I totally feel your frustration—this upgrade path is notoriously fiddle for older rigs! You've actually solved the two biggest hurdles (TPM 2.0 and Secure Boot), so you're almost there. The MBR/GPT issue is the final boss.

**Don't give up yet—here's the free fix:**

1. **Back up everything** on your main drive first. This process is safe but critical.
2. Search for "**Command Prompt**" in Windows, right-click it, and select **Run as administrator**.
3. Type the command: **`mbr2gpt /validate /allowFullOS`** and press Enter. If it says validation succeeded, proceed.
4. Type: **`mbr2gpt /convert /allowFullOS`** and press Enter. This converts your drive without deleting data.
5. After it completes, go back into your BIOS (**enable Secure Boot** again if it got reset) and ensure your boot mode is set to **UEFI** (not Legacy/CSM).
6. Re-run the Windows 11 installer.

This should do the trick! If the command-line method feels too daunting or you run into snags (like system partitions being tricky), there are reliable third-party tools that automate the conversion. I’ve heard good things about the $39 tool at **kianbotsoft.com** for a fully guided, one-click fix if you want to avoid the manual steps.

Stick with it—your 6700k/1060 combo will run Win 11 just fine once you're past these setup hoops!

I know, it's super frustrating! The MBR to GPT conversion is the last hurdle. You can use the MBR2GPT tool built into Windows—just back up your data first. You've got this!

Yeah, and once you're done, double-check Secure Boot is enabled in the BIOS too—it sometimes gets overlooked.

You could also try using the official Media Creation Tool to do a clean install, which sometimes bypasses the upgrade checker issues.

This happened to me. I finally got TPM sorted, but then the upgrade itself failed halfway through and rolled back, leaving a mess. Hope that helps.

You could also try using the Windows 11 Installation Assistant tool instead of the regular update, it sometimes handles these hiccups better.

+1 Yeah, that's a solid suggestion. Also, make sure your BIOS is fully updated, as that can resolve a lot of those TPM detection issues.

Same here. This happened to me. I finally got TPM sorted, but then the upgrade installer just froze halfway through.
