Linux not showing up in duel boot after windws update solved

 Boot in windows

 

open command prompt as administrator

 

bcdedit /set {bootmgr} displaybootmenu yes

 

press enter

 

output should be command completed successfully 

 

now go to advanced settings

 

in the section startup and recovery

 

click settings

 

make sure the time to display list of operating systems is set to 30 seconds

 

go to control panel ,go to power options

 

disable fast startup

 

restart your computer

 

but in my case the problem is not solved

 

still showing just one option windows 11 in boot menu

 

when i have duel boot installed fedora 40 workstation

 

so booted to windows again

 

open command prompt as adminsitrator

 

bcdedit /enum firmware

 

in case of fedora 

you will see

\EFI\fedora\shim.efi

now type

bcdedit /set {bootmgr} path \EFI\Fedora\shim.efi

if this command is successful you will see duel boot menu again

if you want to go back to windows only boot menu

bcdedit /set {bootmgr} path \EFI\Microsoft\Boot\bootmgfw.efi

then you will see windows only boot menu

however to solve this properly

you need to install grub from your linux partition

solve bluetooth issue with broadcam wireless adapter BCM43142 in garuda linux

To solve bluetooth issue

To get the Broadcom BCM43142 Bluetooth working on Arch Linux, install the missing proprietary firmware package from the AUR (like broadcom-bt-firmware),

 enable the bluez service, and reload the kernel module.

Firmware and Driver Setup

Most users on Unix StackExchange agree that the BCM43142 requires extra firmware not present in standard packages.

Install an AUR helper or manually build the package: yay -S broadcom-bt-firmware (or bcm43142a0-firmware).

Restart or reload the btusb kernel module using sudo modprobe -r btusb 

followed by sudo modprobe btusb.

Enabling Bluetooth Service

Install the core Bluetooth software:

 sudo pacman -S bluez bluez-utils.

Start and turn on the system daemon: 

sudo systemctl enable --now bluetooth.service.

Use bluetoothctl to power on the controller and scan for your peripheral devices.

If agent registered messege appeared it is working

install broadcam wireless bluetooth adapter BCM43142 on garuda linux

এমন একটা দিন ছিল যে লিনাক্স অপারেটিং সিস্টেমের কোর্স করছি কিন্তু বাড়িতে ইনস্টল করতে পারি না

যদিও বা করি ড্রাইভার পাওয়া যেত না বিভিন্ন ডিভাইসের ,ইন্টারনেটের যুগে বড় হয়েছি ,নেট কানেকশন না করা গেলে কিসের অপারেটিং সিস্টেম

কোন যুগের কথা ,দুই হাজার চার ,দুই হাজার পাঁচ

তারপর দুই দশক চলে গেল

লিনাক্স এখন অনেক উন্নত ,বেশিরভাগ কম্পিউটারে সব ডিভাইস চিনে ফেলে

কিন্তু বেশিরভাগ ,এখনও সব নয়

একটা পুরোনো ল্যাপটপ কিনেছিলাম ,এইচপি প্যাভিলিয়ন

তার ওয়ারলেস এডাপ্টার ছিল 

সেটা এই কমান্ডে দেখা যায়

Lspci -nn | grep -i net

দেখতে পেলাম BCM43142

অর্থাৎ ব্রডক্যাম এডাপ্টার ,এগুলো সহজে চিনতে পারে না 

ফলে আলাদা করে মডিউল ইনস্টল করতে হলো

Wl বলে একটা মডিউল আছে

Sudo pacman -S linux-zen-headers

Sudo pacman -S broadcam-wl-dkms

Sudo dkms autoinstall

Sudo modprobe wl

না হলে একটা রিস্টার্ট করতে হবে

এখন নেট না পেলে এগুলো করছিলাম কী করে ,স্বাভাবিক প্রশ্ন

ফোন লাগিয়ে ইউএসবি টেদারিং করে 

এবার এতটা পরিশ্রম এক মুহূর্তে হয়নি ,বেশ খানিকক্ষণ চেষ্টা করে তবে সফল হয়েছি ,ফোন আর লাগিয়ে নেট পেতে হচ্ছে না ,wifi কাজ করছে

কিন্তু আর্চ লিনাক্সের একটা এক্সাম্পল এন্ডাভার লিনাক্স ইউজ করলে এইটুকুও করতে হত না

লাইভ বুট করে ও ব্রডক্যাম খুঁজে নিয়ে স্বতঃস্ফূর্ত ভাবে ড্রাইভার নামিয়ে নেয় 

অনেকদিনের একটা সমস্যা মিটলো 

এবার নেক্সট টার্গেট ব্লুটুথ

দেখা যাক

Connect my zeb duke wireless bluetooth headphone using terminal in fedora 40

 install bluez-deprecated 

sudo dnf install bluez-deprecated

hcitool scan

should show the bluetooth devices

if not 

bluetoothctl

agent on
scan on # wait for your device's address to show up here
scan off
trust MAC_ADDRESS (in my case 41:42:FF:71:7A:6B)
pair MAC_ADDRRESS(in my case 41:42:FF:71:7A:6B) 

// the above comment will fail  if the device is already paired
connect MAC_ADDRESS (in my case 41:42:FF:71:7A:6B)

there are simpler ways off course

bluetoothctl devices

this will show the device with the mac address

now if the device is not paired 

bluetoothctl pair 41:42:FF:71:7A:6B

if this succeeds then

bluetoothctl connect 41:42:FF:71:7A:6B

to disconnect

bluetoothctl disconnect 41:42:FF:71:7A:6B

 

 to remove the pairing

bluetoothctl remove 41:42:FF:71:7A:6B

eve-ng web gui login issue solved

df -h




to see you have sufficient space




if you do not have sufficient space you can add another virtual drive




log in eve-ng virtual machine as root

and see if mysql server is working




sudo service mysql status



or

ps aux | grep mysql



if mysql is running



To fix permission, enter this command in eve-ng console

/opt/unetlab/wrappers/unl_wrapper -a fixpermissions



if this does not solve the issue you can restore the db

unl_wrapper -a restoredb



However the issue for me was you can not login using root in web gui in eve-ng

you have to use

username admin

password eve
