No Bootable Media Found

 I stumbled across problem where laptop was not able to boot from SSD which was in perfectly mint condition.

Problem was, that somehow boot sector of drive was corrupted.

Quick set of commands from Hiren's Boot CD successfully rebuilt BCD file and OS was able to boot properly.

Boot to Hiren's Boot CD from USB.

1. Run cmd
2. Run "diskpart" from cmd
3. Select disk where corrupted OS is installed "sel disk <number>"
4. List available volumes by using "list volume"
5. Find volume which is 100MB in size and formatted to FAT32
6. Select found volume by "sel vol <number>"
7. Assign letter K to this volume by "assign letter k:"
8. Exit diskpart by typing "exit"
9. Enter boot folder by using "cd /d K:\EFI\Microsoft\Boot"
10. Change attribute of BCD file so it can be renamed "attrib BCD -s -h -r"
11. Rename BCD file "ren BCD BCD.bak"
12. Rebuild BCD file "bcdboot C:\Windows /s k: /f ALL"

Restart computer, remove USB with HBCD and you should be able to boot into Windows normally.

File Path in Taskbar.xml file

If you try to specify icon layout in taskbar via GPO you are able to use XML file according to MS schema (https://docs.microsoft.com/en-us/windows/configuration/customize-windows-10-start-screens-by-using-group-policy).

One thing that bothered me was that from total of 4 icons only 3 applied. And reason was pretty simple. 

Although Windows is fine with using Forward Slash, Backslash and even both combined, in this case only working scenario is BACKSLASH.

SCCM Application not showing up in Software Center

I have just recently learned why app was not deploying to client the hard way.

So basicaly my scenario:
SCCM Server running on premise
SCCM Distribution Point running on premise
SCCM Console running on SCCM DP
Client in domain, in many collections in SCCM

When I add computer information to SCCM, computer is added to global Collection of All devices.
Then I am able to PXE Boot from DP and via Task Sequence install OS to PC.
During this installation, depending on TS computer is then added to device collections which are then used to deploy applications.
For each application there is device collection

I have AppxPackage which I want to deploy via SCCM and this package is dependent on another 3 packages.
Yet app won't show in Application neither in Installation Status tab of Software Center.

When I ran DeploymentMonitoringTool (which is part of SCCM Client Tools) desired Application was under Deployments, but when I clicked on it, popup saying "DT cannot be empty" appeared and app closed.

All problems were resolved by editing Application->Deployment types and removing Administrator comment from one of DT's.

Dell Mentor Media Unlock Guide

When you buy Dell Laptop/Desktop, in most cases you receive Dell USB Flash Drive, which can be used for OS reinstall/repair. Nowadays, when Windows 10 is widespread and most used Operating System (statistics), USB drives as this are useless. Common idea is to format them and use them as your usual USB pendrive for daily usage.

But that's where this little problem comes in. Dell is actively restricting those pendrives for Read-Only access, so when you try to format them, you probably end with error like this:

But this can be solved by LLF (Low-Level Formatting) this drive.
