1. debian failed to boot 181030

this afternoon the pc stops responding saying

BERT cant request iomem region /dev/sda1

it is mostly associated with fstab, try to disable some partitions and the system may get back to work. run below when folder is not mounted

e2fsck -vf /dev/sdb

it will show many errors, and the errors may be related to bad blocks in the hard disk partition

other things i have tried a. reinstall mbr grub-install /dev/sda b. re-configur grub grub-config -i /root/grub/grub.cfg grub-update

but i do not think these are the reasons

2. use normal lan cable to connect laptop with rpi

3. install for a debian

apt install ipython dh-autoreconf tmux git gcc build-essential gfortran
apt install libx11-dev libssl-dev libssl1.0-dev  # for rdesktop

fzf

apt install python-matplotlib python-pandas python-pip python-requests

4.TO210210 FIX: VirtualBox Error VT x is not available in Windows 10 v1809 (Solved)

Instructions to fix the following error in VirtuaBox: "Failed to open a session for the virtual machine . VT-x is not available (VERR_VMX_NO_VMX) with Result Code: E_FAIL (0x80004005), Component: ConsoleWrap, Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed".

Step 1. Enable Hardware Virtualization in BIOS.

First of all, proceed and enable the Virtualization Technology feature in BIOS settings. To do that, restart your system and launch the BIOS Settings. A. If you own an Intel CPU: Click the Advanced * tab and set the Virtualization (aka "Intel® Virtualization Technology (VT-x)" to Enable.

Note: In some BIOS the Virtualization setting is under the Performance options. B. If you own an AMD CPU: Click the M.I.T. tab –> Advanced Frequency Settings –> Advanced Core settings and the set the SVM Mode (aka "Secure Virtual Machine") to Enable.

Save and exit BIOS settings.

Try to start the VirtualBox machine. If you still face the same error, then proceed below.

Step 2. Disable Hyper-V. *This step applies only to Windows 10 Professional and Enterprise versions.

Navigate to Windows Control Panel and open Programs and Features.

Click Turn Windows features on or off. Then uninstall Hyper-V.

Uncheck the Hyper-V feature and click OK.

Note: If the Hyper-V is not enabled, then try the following trick: Enable Hyper-V –> Restart the computer –> Disable Hyper-V and restart again. When the removal operation is completed, restart your computer.

After reboot, start the VM. You are done.
