When attempting to upgrade to the Windows 10 April 2018 Update, select devices with Intel SSD 600p Series or Intel SSD Pro 6000p Series may crash and enter a UEFI screen after reboot.

Microsoft is working with OEM partners and Intel to identify and block devices with Intel SSD 600p Series or Intel SSD Pro 6000p Series from installing the April 2018 Update due to a know incompatibility that may cause performance and stability issues. If you have encountered this issue, follow the steps to reinstall the previous operating system (Windows 10, version 1709).

Microsoft is currently working on a resolution that will allow the April 2018 Update on these devices in the near future.

Update (6/22/18):

Microsoft has included a solution for this issue in the May 23, 2018 Cumulative Update (KB4100403). This solution prevents the issue from occurring when installing the April 2018 Update. Please note that this solution does not restore systems that have already experienced the issue and are currently booting to a UEFI screen. Any devices already impacted should still follow steps to reinstall the previous operating system (Windows 10, version 1709). Any devices with Intel SSD 600p Series or Intel SSD Pro 6000p Series that have installed the June 12, 2018 Cumulative Update (KB4284835) will no longer be blocked from installing the April 2018 Update.
