the installation failed in the second boot phase

For example, taking error code 0xC190 0102, we will take reference corresponding to 0x00000102 and it means STATUS_TIMEOUT. Similarly, if you got NTSTATUS code, then you need to refer this documentation. Removing the device will help you to resolve the error. This means for error code 0x8007001F, an external device connected to the system during upgrade is blocking the upgrade. Following that, for error code 0x8007 001F, the interpretation of 0x0000001F has to be taken and it is A device attached to the system is not functioning. If you got Win32 code, refer to this documentation for its interpretation. Okay so we now have information about result code. Similarly for 0xC190 0102, last four digits are 0102.

For example, taking 0x8007 001F, last four digits are 001F. Now examine last four digits of result code to identify what it means. While NTSTATUS code starts with C, for example 0x C1900102. Win32 code usually starts with 8, for example 0x 8007001F. A result code could be Win32 code or NTSTATUS code. You have to summarize interpretation of these codes to identify root cause for an upgrade failure. While the second part is 0x4000D, and it will be called extend code. So back to scenario considered above, the error code we got was 0x8007001F – 0x4000D. Your system will be restarted during change of phase. If you got upgrade code that includes 0x4000C, 0x4000D, your upgrade would have been blocked in this phase.

Second boot phase (OOBE boot phase): Upgrade settings are concluded here and at the end of this phase, you’ll spot the familiar account setup animation. Upgrade error containing 0x3000C, 0x3000D shows upgrade blocked in this phase.Ĥ. First boot phase: This can be considered as the first boot of upgraded OS because initial settings are configured now. If this phase is involved in upgrade error, you may see 0x2000C, 0x2000D with error code.ģ. As far as UI is concerned, you’ll see Working on updates during this phase. Required services and devices will be started. Under this phase, a recovery partition will be configured plus a rollback would be established which may help you to downgrade to previous OS if required. Safe OS phase: Most of upgrade errors are seen in this phase. You’ll see ‘Installing Windows’ for this phase on UI.Ģ. Here, only thing ensured is that current OS and upgrade source remains accessible.

Downlevel phase: In this phase, usually upgrade errors are not seen because at this stage upgrade is not started. When an upgrade is performed, it is divided into following four phases:ġ. Understanding Windows Upgrade Error Codes About Upgrade Phases To answer above questions, you should have a quick understanding about upgrade phases and installation blocks and this information is provided below.
