ASP.Net Core Web Application using ADO.Net

A while back, our business decided to diversify the software development using multiple stacks & against few available options, opted for .Net Core, mainly because it is Microsoft supported platform. As we were always using Oracle products, mainly Oracle Forms & reports, needed a sample project that could be mapped to 50-60% Oracle Forms behavior to address the difficulties our users might face, especially with list of values.

I came across a student who readily accepted our proposal and came up with a wonderful sample, that I am sharing with .Net Core aspirants.

Oracle VirtualBox | BdsDxe: failed to load Boot “Windows Boot Manager”

On By windows7bugsIn Oracle VirtualBoxLeave a comment

Okay, I use many Virtual Machines, mostly for Sandbox purposes & few out of curiosity.

Recently, I ran out of space on my Windows 11 Vdi & had to convert the fixed size Vdi to dynamic to extend the size. As I didn’t want to re-install the OS, I used GParted to resize and rebuild the partitions. Once done, during the booting, I started getting some interesting failure notices, without affecting the normal loading process.

BdsDxe: failed to load Boot0004 "Windows Boot Manager" from HD ....
BdsDxe: failed to load Boot0003 "UEFI VBOX ...."

I did a quick search and couldn’t find a solution immediately and forgot about it until yesterday, when I read about Microsoft’s decision to bring back Taskbar Anywhere feature ;). I wanted to join the insider program again and these messages were quite annoying as I had to reboot the VM multiple times.

My solution may not be suitable for you, however, giving it a try will not hurt!. I removed both the Hard Disks from the VM and attached them once again. Next reboot was clean, without showing these failure messages.

Oracle VirtualBox version: 7.2.14
