Grub Rescue: no /boot directory, cannot boot

I got a new laptop and am trying to move my dual-boot SSD into the new machine. However, I get thrown into the grub rescue terminal when trying to boot. I've tried following many guides, but I cannot proceed past the insmod stage, as I cannot find it on any of the hd0 partitions. My grub is on (hd0,gpt6) and all the guides I've read say to set the prefix to something like (hd0,gpt6)/boot/grub). I do not  ...

Hopefully the title makes sense.

All I need to know is if there is a way to make the thumbnails/image previews bigger as on a laptop screen they are pretty hard to see.

touchpad only works on certain reboot conditions/can't be bound to driver (Ideapad Flex 5 14ARE05 AMD)
mu flag

My laptop has a bug where when you try to suspend ubuntu will immediately start back up again and core 0 is locked at 100%.

If at this point you force shutdown by holding down the power button and boot afterwards, the touchpad works.

In the logs you can see this when it gets detected:

kernel: input: MSFT0001:00 04F3:3140 Mouse as /devices/platform/AMDI0010:03/i2c-1/i2c-MSFT0001:00/0018:04F3:3140.0002/inp ...

After reformatting HDD, error "Kernel panic - not syncing: Attempted to kill init!"
cn flag

While transferring documents to a USB flash drive, the eMachines 732 computer running Windows 10 (Home edition) had crashed and would not reboot. Next, a SATA HDD was used, reformatted to exFat to install Ubuntu 20.04 and got the above error. On retrying with a fresh HDD, reformatted to NTSF, the Ubuntu installation stopped, again with the same error. How should one get to a command line prompt?

However, while this command runs, everything else on the machine gets very unresponsive.

Is there another way how to throttle the deletion of millions of subdirectories? ...

Wacom Intuos Pro M Scroll Wheel

I own a Wacom Intuos Pro M and I'm wondering how to use the ring wheel of the pad as a mouse scroll wheel on Ubuntu 21.10 (gnome).

In Ubuntu wacom settings I would like to map the ring wheel to the mouse scroll wheel event (not a keystroke) but I can only assign keystrokes.

In macOS and Win I use the ring wheel a lot, to scroll through the browser pages, zoom in/out in software like Photoshop etc. it seem ...

How to install other dependent packages through apt during the installation of the deb package
ao flag

I try to make a deb installation package by myself, and this deb package needs to install some dependent packages, but when I execute the command "apt install" in the preinst script, I will report this error: error processing archive testDeb_1.0.0_i386.deb (--install):nd. It is held by process 28 (dpkg)

How can I install other dependent packages during the deb process?

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
