Windows 7: MS Update KB3033929 Causing Reboot Loop

MS Update KB3033929 Causing Reboot Loop

One of the operating system updates Microsoft released on Tuesday of this week — KB3033929 — is causing a reboot loop for a fair number of Windows 7 users, according to postings on multiple help forums. The update in question does not appear to address a pressing security vulnerability, so users who have not yet installed it should probably delay doing so until Microsoft straightens things out.

Windows 7 Pro-x64

I didn't have a problem with this update but I don't have a dual boot system either.


Issue 1

Some users cannot install this security update if their computers meet the following conditions:
  • Have a multiple-boot configuration of Windows and various distributions of Linux
  • Use a non-Windows boot loader
  • Have Windows and Linux installed on separate drives
We have been able to verify that systems that have the Windows boot loader enabled as the primary loader are successfully able to install this update and that systems that have a non-Windows boot loader specified as the primary boot loader cannot install the update, even if the user uses that loader to select Windows.

Issue 1 workaround

To work around that issue, you can either use Windows as the default boot loader or you can change your BIOS settings to enable the Windows boot loader directly when you install this update.
