Booting to Recovery Environment (WinRE)

There are two different recovery environment in windows WinRE and WinPE. The most basic remainder between the two is that WinPE includes network capabilities that is not available in WinRE. In this tutorial, we are going to focus on WinRE .
There is a few different ways to get in to WinRE, the most know one is probably to press F8 a boot. however missing that magic trick half a second where that option is available has happened to all of us .
Another thing you can do is if you can actually boot to the OS is open a command prompt an enter shutdown /r /o /t 0 .

/r is for boot. /o is boot to windows recovery mood and /t is clock time 0 seconds
You can besides hold down fault while clicking restart in the graphic interface .

naturally, you can besides do it the old school manner, where you boot to bios and choose to boot to a videodisk drive with a initiation videodisk, there from there chose to run WinRe tools .
ultimately, Windows will automatically boot to WinRE under sealed conditions :

• Two Bad startups – This is when something in the process of the OS startup go wrong.
• Two sudden shutdown – This is when the OS is suddenly shutdown like the power are cut.
• Secure Boot Error – This could be if something like a rootkit tries to fiddle with the secure boot.

Startrep

1. Click Troubleshoot
2. Click Command
   Prompt
3. Type cd
   /sources/recovery
4. Type startrep
   and press Enter

Startrep is a program, which diagnose the inauguration work and if possible fixed it. I looks at register corruptness, driver issues, partition problems and other. therefore, it is always a well locate to start .

Bootrec

Another utilitarian besides is bootrec .

• /Fixmbr
  – Will write a Master boot record for windows to boot on.
• /FixBoot
  – Will write new boot sector.
• /ScanOs
  – Scan all partitions to look for at boot records.
• /RebuildBcd
  – Will allow you to choose the versions of windows you want to add to the bcd
  store.

Dism

Every once in a while Microsoft fucks up with a Windows update that send servers into bsod when boot or something worse. In these situations, you can use Deployment Image Service and Management Tool ( DISM ) from WinRE to remove the update. Start by searching the internet for recent windows updates for your OS, and if early people have had like problems with it. Find the KB count of that update .

1. To see all installed updates type Dism /Image:C:\ /Get-Packages
2. To remove a KB type Dism /Image:C:\ /Remove-Package /PackageName:Package_for_KB######
3. To reboot type shutdown /r /t 0

Hopefully, Windows will boot successfully afterwards.

Diskpart

Diskpart can be used to check the state of your disk and partition. If you boot up and you get a screen like the on below saying that the engage system could not be found, this is a beneficial locate to start .

Since the OS in is gone, we can ’ deoxythymidine monophosphate consequence get to WinRE we need to dust off out Windows 2012 r2 Installation disk or iso charge and boot from that .

1. Choose your keyboard layout and click Continue
2. Click Repair
   your computer

• Once in WinRE Click Troubleshoot
• Click Command
  Prompt
• Type Diskpart | List disk | Select disk 0 |List partition | Select
  partition 1 |  Detail
  partition

so I we see that the partition has the impute Activ:No. Since this is the only partition in our system this is probably not a good mind that it ’ mho inactive .

• Type Active

• Type Exit
  to leave diskpart and Exit again to
  leave command prompt
• In WinRE Click Continue to reboot

Hopefully windows will immediately boot to the active partition.
