You haven't got the minimum hardware requirements ; https://help.ubuntu.com/community/Installation/SystemRequirements ; you've asked this before (only it was Unity 7; where you have half the minimum screen memory required for that too). The requirement as mentioned in prior link applied to 17.04 & later; ie. before the 2017-April release and since. 18.04 is the 2018-April release so the minimum wasn't reduced. 128MB is < 256MB minimum requirement & 3D acceleration is required.

Use a *lighter* flavor, yes Ubuntu 18.04 LTS desktop is fully supported (unlike *flavors*), however even if you get it *running* it won't be *fast* or *fun* to use in my experience... I've got boxes used in QA-testing that date from 2004 that I stopped testing Ubuntu Desktop *long ago* because they lack resources (like your box), where as the Ubuntu *flavors* or Ubuntu Server they are *fun* & *fast* as the resource requirements are so much less.

Your system requirement do not meet for ubuntu . try increasing the RAM. then try Host+R to reboot vm do this 3-4 times then it should boot normally

it fixed for me.

OR you can also use a light flavour such as Lubuntu

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
