hard drive – Bootcamp – Windows 10 – No bootable device — insert boot disk and press any key

I have got a problem with booting into Windows 10 after changing Superdrive to SSD – “No bootable device — insert boot disk and press any key“.
It works if i leave only old hard drive, removing the new SSD, the Windows boots well.

The boot option screen can detect old MacOS, new MacOS and the partition with Windows on old HD.

The primary OS is on SSD /dev/disk0 and the Windows in on HD /dev/disk1s4.

$ diskutil list

I’ve read tons of similar topics, but unfortunately wasn’t able to figure out the fix.
I really hope someone can advise.

Thank You.

hello everyone in this forum.
ok, here we go first with what is the issue.
so i was going to install linux mint on my laptop, was of the idea that it would work for what i need my laptop for,only it didn’t as i’m not very smart when it comes to linux in the first place. so i was trying to create a bootable usb on that laptop for windows10 again only i did something wrong and now linux is of my laptop also, so there’s no OS on it anymore. The only thing i have left is a paspberry pi4. now my question is, the raspberry pi has Kali linux on it, can i create a bootable usb for windows with this small pc or am i stuck? If it would be possible, please if you are willing to help me the advice you are willing to give will be needed to be step by step as i’m a noob.

How to boot up two VirtualBox VMs with the same DVD ISO file?

The path /Users/runner/work/fedora-coreos-vm/fedora-coreos-vm/next_just_a_test is a DVD ISO file. I would like to use it to boot up two VMs with VirtualBox.

How can I do it in an efficient way? (Preferably minimizing RAM memory and disk usage).
I get an error message:

How to design a rest api for updating collection(ArrayList) of Resource in Spring boot?

I have a resource called Client and it has the following attributes id, name, redirect URLs(ArrayList).

class Client{
   int id;
   String name;
   List<String> redirectUrls;

I have all CRUD http request mappings over resource Client. In the get method I fetch the resource from database and give to client, however my firewall blocks the put requerst when user submits the put request to update the resource since it carries collections of urls(redirectUrls) within the request body.

So, I have this requrement to design an API only to update the collection of given Client. Let’s say for a given Client I have 10 redirectUrls(loaded in the Client UI) and as soon as the client adds a new redirectUrl, my client calls this new API with the redirectUrl and it gets added to collection in the backend. At any given point of time when client adds new redirectUrl the API gets called.

The question here is how should I design my API so that only this particular attribute(redirectUrl list) gets updated with the coming redirectUrl. One option is PATCH API but this one should ideally replace the whole attribute value with new vlaue, which is not what supposed to happen in my case.

Any help is much appreciated. Thanks.

ubuntu – Unable to fix dual boot (grub menu)

I have dual boot with Windows10 and Pop OS, after last upgrade of Pop OS appeared grub menu and I only be able to continue writing “exit”. After that boots in Pop OS (Ubuntu based), but I cannot boot in Windows.

I’ve tried “Recommended repair” using boot repair application and what suggested here

I don’t know how to proceed to fix this. Thanks for any help

ubuntu – Laptop not entering dual boot menu after crash of one OS

I was running Ubuntu 21.04 on my Lenovo T480 Thinkpad, and the device froze. After pressing the power button to reboot, it started to the normal Lenovo splash screen, and offered the bios menu. The bios menu option disappears after five seconds.Typically it would progress to a a dual boot screen then, where I can choose to boot Ubuntu or Windows, but now the computer stays on the splash screen until I reset it by pressing the power button.

I can bypass the dual boot menu by launching windows via the bios menu, but if I attempt to launch Ubuntu using this same method, the computer screen stays black until it’s reset by the power button. None of the function keys have any effect

Since then, I’ve applied a firmware update, performed system checks in the bios menu, and removed my laptop batteries and performed a power drain, but none of those worked. Does anyone have advice on other strategies I could use to try to get things working? I would appreciate any help

security – Dual Boot Windows 10 Pro Advice for 2021

My long-time Macbook which I used as a development and business workstation just died on me and I cannot afford to replace it just now. I have a pretty decent windows gaming system that I would like to dual-use for a while but I need to lock it down and partition it’s gaming and business functionality pretty tightly.

If this is the wrong place to post this, or there is a better place, please let me know. Other relevant post were old and had little-to-no community input.

What I am considering is dual booting two separate windows 10 pro licenses, using TPM/Bitlocker with the business in the front, and a largely open sandbox install as the party in the back.

I’m no seasoned certified windows admin, but I know my way around pretty well and my bing-fu isn’t atrocious, but what I’m looking for is any input from people who may have set up the same or similar and succeeded (or failed) on whether this is even a viable approach before I spend 10-100 hours mucking about with it.

What I have to work with:

- 1 Windows 10 Pro Retail License
- 1 Windows 10 Pro Upgrade License from:
    ○ 1 Windows XP Pro Retail License
    ○ 1 Windows 7 Pro Upgrade Retail License
- AMD Ryzen 5 3600 (Virtual TPM)
- 2 NVME Drives
- A couple low-wear HDD Drives

What I am anticipating it to look like and what I’ll use it for:

  SystemName: "The Brain"
  Purpose: "Business, Development and Secure Correspondence"
  CoreTech: "WSL2, Git, Office, VSCode, GPG, SSL, Teams, Figma"
  Users: "Me"
  SystemName: "Pinky"
  Purpose: "Gaming, Modding Games, 3D/2D Art, Running Sus Apps"
  CoreTech: "Bethesda Games, Paradox Games, Krita, Inkscape, Narf!"
  Users: "Me, Fiancée, Drunken Me"

  DriveName: "NVME1"
  Size: ">475GB"
    VolumeName: "System - The Brain (C:)"
    Size: "125GB"
    Use: "Windows Applications, Settings, User Root"
    BitLocker: True
    VolumeName: "Data - The Brain (D:)"
    Size: "200GB"
    Use: "User Documents, OneDrive"
    Bitlocker: True
    VolumeName: "System - Pinky (C:)"
    Size: "125GB"
    Use: "Windows Applications, Settings, User Root"
    BitLocker: False

    BitLocker: False

    VolumeName: "Archive - The Brain (A:)"
    Size: ">475GB"
    Use: "Local Project Archive, Local Library Archive"
    BitLocker: True

  DriveName: "HDD2"
  Size: ">475GB"
    VolumeName: "Archive - Pinky (A:)"
    Size: ">475GB"
    Use: "Archived Games, Archived Mods, Reference Photos/Videos"
    BitLocker: False

I have some other HDDs and maybe a SSD or two should I need them.

Any thoughts on best practices to go about this?

Is there a visual bootloader I could use instead use f8/msconfig to swap between them (ala apple bootcamp)?

Can I shield The Brain’s filesystem completely from Pinky? Everything will be backed up on premises and through a few cloud machinations, but I’d love a way to lock down completely.

I won’t really be running suspect applications – but some of the tools used in the modding community aren’t exactly easily auditable or in anyway verified as entirely on the up-and-up. I’ll use a proper container or vm instance if I’m genuinely doing something Narf!

I know I shouldn’t $h*t where I eat, but for now this is what I have to do.

Appreciate any constructive thoughts or guidance, and if I’ve left anything out let me know.

partition – Dual boot Yosemite and Big Sur (HFS, APFS and other potential challenges)

I’d like to use a clean install of the latest Big Sur (11.4) on a machine that currently has Yosemite installed. I’d like to keep using Yosemite due to some legacy apps/licenses.

  • Ideally I’d like to edit the same files from both Yosemite and Big Sur
  • I’ve also considered accessing data and installing/running an app on a different partition to the one with the OS
  • However, I’m realising that there could be challenges due
    to the HFS and APFS formatting

I have Yosemite (10.10.3) installed on the Macintosh HD partition. I have two other partitions which I use as data storage (e.g. Word, Excel files).

P1) Macintosh HD (480GB, Yosemite already installed)
P2) 2 - 430GB
P3) 5 - 90gb

Scenario (i):

P1) Macintosh HD (480GB, Yosemite already installed)
P2) 2 - 430GB (Big Sur would be installed)
P3) 5 - 90gb

Scenario (ii):

P1) Macintosh HD (480GB, Yosemite already installed)
P2) 2 - 430GB 
P3) 5 - 90gb (Big Sur would be installed)

All three partitions according the disk util are:

   File System Personality:  Journaled HFS+
   Type (Bundle):            hfs

Question that arises:

  1. With reference to the two scenarios above, is it possible to access (both read & write) files (e.g. a Word document) and or run apps stored on a different partition than the one with the running OS?…Or will the partition (with the other OS installed) no longer be visible?

A.) If yes, how does this work if one of the drives is JHFS+ and the other is APFS?

B.) If not, would it be better to store data on a partition that doesn’t have any OS installed (used almost like an external SDD except that it’s internal)?

C.) Would there be any issues from installing apps not on the same partition as the one with OS-installed? E.g. app files that need to be located in the system, caches, application support and library folders
