If you want to know what Downlevel, Safe OS, First Boot, and Second Boot Phases are in a Windows Upgrade process, then read this post. An upgrade moves your system from an existing version of Windows to a new version. It can also migrate your system from one edition of a Windows version to a different edition of the same version. When this happens, a lot of changes take place internally.
Downlevel, Safe OS, First Boot, Second Boot Phase explainedThere are 4 key stages involved in an in-place Windows upgrade process: Downlevel, Safe OS, First Boot, and Second Boot. An in-place upgrade installs a new version of Windows without removing the previous version from the system. This type of upgrade scans the system for new OS compatibility and then uses the Windows Setup application to install the new version from an installation media, such as a USB key, a mounted .ISO file, a network device, or a DVD.
The Windows Setup application is a bootable installer program that upgrades a system to Windows 11/10 or performs a clean installation. While performing a system upgrade, it goes through 4 different phases:
Downlevel Phase
Safe OS Phase
First Boot Phase
Second Boot Phase
Let us understand these phases one by one.
1] Downlevel PhaseDownlevel phase is the first phase of the Windows upgrade process. It runs on the existing OS and checks the system for new OS compatibility, such as available RAM (1Gb for 32-bit, 2Gb for 64-bit), primary storage class drivers, network class drivers, drivers for hardware not currently connected to the system, inventory products, and patches, etc. It then uses Windows Updates to install the latest updates if not already present in the Windows Installation Media download. Then compares the inventory for database compatibility. And administers boot-critical drivers into Windows Recovery Environment.
2] Safe OSAlso known as the setting up phase, this is the second phase in the Windows upgrade process. During this phase, a backup of the downlevel OS is created to switch to the old OS if required. This basically includes hard links to already existing content. Some drivers are administered into the new OS which is then laid down on a disk in a folder hierarchy. Some offline mitigation tasks are also performed during this phase.
3] First BootNext is the First Boot phase. During this phase, an instance of the new OS is created and bound to the machine. Then 1st boot to the new OS is performed and initial settings are applied. Installation of drivers, migration of applications, and some other migration tasks are also performed during this phase.
4] Second BootAlso known as the OOBE (Out-Of-Box Experience) boot phase, this is the last and final phase in the Windows upgrade process. During this phase, 2nd boot to New OS (or clean boot to the final OS) is performed and final settings (hardware and software configuration settings) are applied. Windows Welcome Screen appears when the user starts the system for the first time and is prompted to enter his account information, choose language, accept Microsoft Terms of Service, set up a network, set up sign-in with Windows Hello, etc.
After each of these phases, the system reboots to apply changes. This winds up Downlevel, Safe OS, First Boot, and Second Boot Phases explained. Hope you find the information useful.
Where are Windows 11 install logs?When you upgrade from an earlier version of Windows to a new version, several log files are created during each phase of the upgrade process. These log files correspond to a successful or a failed upgrade and help determine what went wrong with the upgrade. You may find some of these log files at C:$Windows.~BTSourcesPanther, C:$Windows.~BTSourcesRollback, and C:$Windows.~BTSourcesPantherUnattendGC.
What is the OOBE screen in Windows?OOBE, also known as the Out-Of-The-Box Experience screen, is the first screen you see when you turn on your computer after a successful Windows upgrade. This screen guides you through a series of steps to set up Windows using a local account or a Microsoft account and proceed with standard settings of the Windows 11/10 OS.

How To Boot Into Xolo Q1010 Recovery Mode
What is Recovery?
A recovery is a separate bootable partition on your Android device that you can use to install system updates and repair (factory reset) your device. A lot more can be done using a custom recovery, but the stock recovery that comes pre-installed on your Android device is limited to these features only. And FYI, these features are integrated into the Android OS as well — when you chose to factory reset your device from device settings or install an OTA update, your device reboots and boots into the stock recovery to finish the job.
The stock recovery that comes pre-installed on your device doesn’t support touchscreen mechanism. You’ll have to use the Power and Volume buttons available on your device to select and navigate between options in the recovery.
There are multiple methods to boot your Xolo Q1010 in recovery mode. The most handy (and hardware coded) method is about pressing a combination of keys for a few seconds on your Xolo Q1010 . Others are software based, let’s have a look them below:
1) Boot into Xolo Q1010 Recovery Mode Using
HARDWARE BUTTONS
This method is a fail-proof method that’ll always work for you, unless you’ve broken one of hardware keys. In such a case you’d be left with only the other two methods discussed below.
Power off your device and wait 4-5 seconds after lights go off.
└ In recovery, use Volume Up and Down keys to navigate between options and Power key to select an option.
[ad1]
2) Boot into Xolo Q1010 Recovery Mode Using
ADB
[ad1]
ADB stands for Android Debug Bridge, a tool used to send terminal commands to a Android device via a PC command line. ADB requires a bit of setup, but it gets the job done with much lesser effort than hardware buttons, so pretty useful in cases when you’ve to boot in recovery mode frequently. Also, if (for some reason) your hardware buttons aren’t working than this is a very good alternative to boot into recovery mode.
And make sure you’ve proper drivers installed for your device. You can download driver from this page →
Extract the file (ADB chúng tôi you downloaded from the link above to a separate folder on your computer
Prepare your phone
Enable developer options: Go to your phone’s Settings » select About phone » Scroll to the bottom and tap on “Build number” seven times to enable developer options
Enable USB Debugging: Open phone’s Settings » select Developer options » Tick the “USB debugging” checkbox (under Debugging section)
└ If the script shows any error than that means either your device is not connected or you don’t have proper driver for your device installed on your PC. For help with driver, check this page →
FYI, the ‘Boot into Recovery Mode.bat‘ script file that we used above to boot your device into recovery mode just uses one line of command:
adb reboot recoveryIf you already have ADB setup on your computer and you know how to use it, then you may just use the command given above to boot into recovery mode.
3) Boot into Xolo Q1010 Recovery Mode Using
Quick Boot (Reboot) APP
Yes! There’s an app for rebooting your phone into recovery mode, and it’s the most easier of the methods we discussed above. But it won’t work unless you’ve root access on your device, and since not everyone roos their device, we’ve put this as the last method here.
ROOT ACCESS REQUIRED
Open the app and grant Root Access
Select ‘Recovery‘ from the list of options and it’ll boot your device into recovery mode
That’s all.
How To Deploy Windows 365 Boot To Your Endpoints
Windows 365 Boot is a feature of Windows that allows administrators to configure a PC such that when the user signs into their physical PC, they are directly signed into their Windows 365 Cloud PC on their physical device. The process becomes seamless if IT admins enable single sign-on for their Cloud PC. This post will share how to deploy Windows 365 Boot to your endpoints.
